Instructions

1. 1

   Heat the grill

   Preheat the grill to medium-high.

2. 2

   Season the vegetables

   Brush the mushrooms, peppers, courgettes and onion generously with olive oil. Season with oregano, salt and pepper, then brush them with some of the basil pesto, reserving the rest for serving.

3. 3

   Grill the vegetables

   Grill the vegetables on both sides until charred and tender, about 4–5 minutes per side. Take them off the grill and, if needed, cut them into smaller pieces.

4. 4

   Prepare the bread

   Split the ciabatta loaf in half lengthways. If you like, grill or toast it until warm and lightly crisp.

5. 5

   Assemble the sandwich

   Spread goat's cheese over one half of the ciabatta, then add the rocket or mixed leaves and grilled vegetables. Add more pesto, or a sauce of your choice, and place the other half of the loaf on top.

6. 6

   Cut and serve

   Use a serrated knife to cut the sandwich into four portions. Serve warm.

What is a grilled vegetable sandwich?

This is an American-style sandwich built around grilled vegetables rather than sliced meat. The combination of charred produce, greens and cheese makes it substantial enough for lunch or a casual dinner.

Here, pesto brings basil and savoury richness, while herbed goat's cheese adds a tangy, creamy contrast. Ciabatta gives the filling a sturdy base.

Nutrition and macros by portion

The nutrition label shows one serving as written: 708 calories, 25g protein, 71g carbs, 37g fat.

The bread and vegetables provide most of the carbohydrates, while the olive oil, pesto and goat's cheese contribute much of the fat. Goat's cheese also supplies protein, along with a smaller contribution from the bread and vegetables. Pair a sandwich with extra salad leaves or other fresh vegetables for a balanced plate.

Choosing and preparing the vegetables

Portobello mushrooms: Their broad caps grill well and bring a hearty, savoury bite. Trim the stems as directed so the caps sit neatly on the grill.

Courgettes and onion: Cut the courgettes into long strips and the onion into rounds so they are easy to turn and layer in the bread. Keep the onion rounds intact while grilling where possible.

Peppers: Halving and removing the stems and seeds makes them straightforward to grill and layer. Brush all the vegetables with oil so the seasoning and pesto cling.

Getting the char right

Medium-high heat helps colour the vegetables while they cook through. Grill each side for about 4–5 minutes, checking for darkened patches and a tender texture.

The vegetables may finish at slightly different times, depending on their thickness and the heat of the grill. Remove each piece when it is charred and tender rather than waiting for everything to finish together.

Using the pesto

Pesto goes on before grilling to season the vegetables, but reserve some for the assembled sandwich. That final layer gives the bread and filling a fresh basil flavour.

Spread pesto rather than pouring it into one spot, which helps distribute its flavour across the sandwich.

Building a sandwich that holds

Bread: Ciabatta is sturdy enough for the juicy vegetables and creamy cheese. Toasting or grilling it is optional, but gives it a warm, lightly crunchy surface.

Layers: Start with goat's cheese, add the greens, then arrange the vegetables and finish with pesto. Cutting with a serrated knife helps slice through the crust without squashing the filling.

What to serve alongside

Serve the sandwich warm, while the vegetables are freshly grilled and the bread is still crisp if toasted. A simple green salad or a bowl of soup makes an easy accompaniment.

Because the filling is rich with pesto and goat's cheese, a lightly dressed side can provide a fresh contrast.

Recipe notes & tips

• Cut the courgettes into even strips so they cook at a similar rate.
• Keep some pesto back for the assembled sandwich rather than using it all on the vegetables.
• Grill the vegetables in batches if the grill is crowded.
• Let the vegetables sit briefly after grilling so excess moisture does not immediately soak the bread.
• Use a serrated knife and a gentle sawing motion to cut through the ciabatta.

Variations

• Swap the bread: Use sourdough instead of ciabatta for a different crust and crumb.
• Change the greens: Choose rocket for a peppery note or mixed leaves for a milder bite.
• Use another sauce: Replace the reserved pesto with a favourite sauce, as suggested in the method.
• Add extra char: Toast or grill the split ciabatta before assembling for a warm, crisp base.
• Vary the vegetables: Use the same grilling method with other suitable vegetables you have to hand.

Common mistakes to avoid

• Crowding the grill: Vegetables can cook unevenly; grill them in batches if needed.
• Skipping the oil: The seasoning and pesto may not coat the vegetables evenly; brush them generously before grilling.
• Overcooking the vegetables: They can become too soft to layer neatly; remove them once charred and tender.
• Using all the pesto before assembly: There may be none left for the bread; reserve some before brushing the vegetables.
• Pressing too hard while cutting: The filling can slip out; use a serrated knife and a light sawing motion.

How to store

For the best texture, store leftover grilled vegetables separately from the bread, greens, cheese and pesto in covered containers in the fridge, and assemble just before serving. Use within 3 days and reheat the vegetables until hot in a pan or on the grill; keep the greens and bread separate until assembly.
