Ingredients

For the grilled vegetables:

1 medium zucchini, sliced lengthwise into ¼-inch thick strips
1 small eggplant, sliced lengthwise into ¼-inch thick strips
1 red bell pepper, seeded and quartered
1 yellow bell pepper, seeded and quartered
1 red onion, sliced into ½-inch thick rounds
2–3 tbsp extra-virgin olive oil
Salt and freshly ground black pepper to taste

For the panini:

4 ciabatta rolls or focaccia squares, sliced horizontally
½ cup basil pesto (homemade or good-quality store-bought)
8–10 oz (225–280g) fresh mozzarella, sliced
½ cup oil-packed sun-dried tomatoes, drained and roughly chopped
Handful fresh basil leaves
Extra-virgin olive oil for brushing
Optional: flaky sea salt for finishing

Instructions

Fire up the grill — Preheat your grill (or grill pan) to medium-high heat. Brush both sides of all vegetable slices lightly with olive oil and season with salt and pepper.
Grill those beauties — Grill vegetables in batches: zucchini and eggplant 3–4 minutes per side, bell peppers 4–5 minutes per side, onion 4 minutes per side—until tender with nice char marks.
Cool and prep — Transfer grilled veggies to a plate and let cool slightly. Pat dry with paper towels if needed to remove excess moisture.
Slice the bread — Cut ciabatta rolls horizontally. If they’re very thick, gently press down to flatten slightly for better pressing.
Spread the love — Generously spread basil pesto on the cut sides of both top and bottom halves of each roll—don’t hold back!
Layer like an artist — On the bottom half, layer grilled vegetables (cut peppers and onions to fit if needed), then add sun-dried tomatoes, fresh mozzarella slices, and a few basil leaves.
Close it up — Place the pesto-covered top half on each sandwich. Lightly brush the outside of the bread with olive oil for golden crispiness.
Press to perfection — Preheat panini press (or heavy skillet over medium heat). Place sandwiches in press or skillet. If using skillet, place a heavy pan on top to press down. Cook 4–6 minutes until bread is golden and cheese is melty.
Rest and slice — Remove panini and let rest 1–2 minutes so cheese sets slightly. Slice each sandwich in half diagonally for that classic look.
Serve hot and happy — Arrange on a platter, sprinkle with a pinch of flaky sea salt if desired, and serve immediately. Pair with a simple green salad or chips—pure Italian sandwich bliss!

Notes

If no panini press, use two skillets: one to cook, one weighted on top. Grill veggies a day ahead for faster assembly. Use high-quality pesto—homemade is best but great store-bought works too.

Recipe Tips and Tricks

Grill vegetables in batches on high heat for nice char marks without overcooking—keep them slightly firm.
Pat grilled veggies dry with paper towels to prevent a soggy panini.
Spread pesto generously on both bread slices for maximum flavor distribution.
Use a panini press if you have one; otherwise, a heavy skillet + weight (cast-iron pan) works great.
Brush the outside of the bread lightly with olive oil for extra golden crispiness.
Don’t overstuff—aim for even layers so it presses nicely and cooks evenly.
Let the panini rest 1–2 minutes after pressing so cheese sets slightly before cutting.
Slice on the diagonal for that classic panini look and easier eating.

Ingredients Notes

Ciabatta or focaccia rolls provide the ideal airy, crusty base that crisps beautifully when pressed. Fresh vegetables—zucchini, eggplant, bell peppers, and red onion—become sweet and smoky when grilled.

High-quality fresh mozzarella (fior di latte or buffalo) melts into creamy pockets. Homemade or store-bought basil pesto adds herby, garlicky richness—use a good one with real Parmesan and pine nuts.

Sun-dried tomatoes (oil-packed for softness and flavor) bring concentrated tang and umami. Extra-virgin olive oil is essential for grilling and brushing the bread.

Fresh basil leaves and a pinch of flaky sea salt elevate everything. Simple, fresh, high-quality ingredients shine here—no complicated sauces needed.

Variations and Substitutions

Swap mozzarella for provolone, fontina, or vegan cheese for different melt or dairy-free option. Add grilled portobello mushrooms or asparagus for extra veggies. Include thin slices of prosciutto, salami, or grilled chicken for a non-vegetarian version.

Use arugula or baby spinach for peppery greens. Swap pesto for tapenade, roasted red pepper spread, or aioli. Try different breads—sourdough, focaccia, or whole-grain rolls. Add roasted garlic cloves or caramelized onions for deeper sweetness.

For spice, include pepperoncini or chili flakes. Make it lighter by brushing bread with less oil or using a contact grill. This recipe is very forgiving—customize with whatever seasonal veggies or pantry items you love while keeping the Italian spirit.

Storage Options

Best enjoyed fresh and hot! If you have leftovers, wrap tightly in foil and refrigerate up to 2 days. Reheat in a 350°F (175°C) oven or panini press/skillet until warmed and crisp (5–8 minutes).

Do not microwave—bread becomes soggy. Unassembled grilled veggies and pesto keep in the fridge 3–4 days; assemble fresh when ready to eat. Not ideal for freezing due to texture changes in bread and cheese.
