Ingredients
- 2 ciabatta rolls or whole-grain sandwich bread
- 1 medium zucchini, sliced
- 1 red bell pepper, sliced
- 1 small onion, sliced
- 1 cup fresh mozzarella cheese, sliced
- 1/4 cup pesto sauce
- 2 tablespoons olive oil
- Salt and pepper to taste
Instructions
- Prepare the Vegetables: Preheat your grill or grill pan over medium heat. Toss the zucchini, bell pepper, and onion in olive oil, and season with salt and pepper.
- Grill the Veggies: Place the vegetables on the grill and cook for about 5-7 minutes, or until they are tender and have grill marks. Remove from heat.
- Assemble the Panini: Spread pesto on one side of each ciabatta roll. Layer the grilled vegetables and mozzarella cheese on top of the pesto. Close the sandwich with the other half of the ciabatta roll.
- Grill the Panini: Place the assembled sandwich back on the grill or in a panini press. Grill for 3-5 minutes, or until the bread is golden brown and the cheese is melted.
- Serve: Cut the panini in half and serve warm. Enjoy your delicious grilled veggie panini!
Cook’s tips
- Preheat the grill or panini press well before adding the vegetables and sandwiches to ensure nice char marks and even cooking.
- Slice the vegetables uniformly (about 1/4‑inch thick) so they cook at the same rate and fit neatly in the panini.
- Use a paper towel to pat the mozzarella slices dry before assembling – this prevents excess moisture from making the bread soggy.
- If you don't have a panini press, use a heavy skillet or a grill pan and press the sandwich down with a spatula or a second pan.
- For extra flavor, brush the outside of the bread with a little olive oil before grilling to help achieve a golden, crispy crust.
Substitutions
- Use whole‑grain sandwich bread or a baguette instead of ciabatta rolls.
- Swap the mozzarella for provolone, fontina, or a dairy‑free cheese alternative.
- Replace the pesto with sun‑dried tomato spread or a basil‑oil blend for a different twist.
- Add other grilled veggies like eggplant, mushrooms, or asparagus to the filling.
- Use a store‑bought or homemade pesto – either works well.
Storage & reheating
Store any leftover panini in an airtight container in the refrigerator for up to 2 days. To reheat, place the sandwich in a panini press or a skillet over medium heat for 2‑3 minutes per side, or until warmed through and the bread is crisp again. Avoid microwaving as it will make the bread soggy.
Frequently asked questions
Can I make this panini ahead of time?
It's best enjoyed fresh, but you can grill the vegetables and assemble the sandwiches in advance. Store the assembled (ungrilled) paninis in the fridge and grill them just before serving.
What if I don't have a panini press?
No problem! Use a grill pan or a regular skillet. Place the sandwich in the pan, then press it down with a spatula or another heavy pan to achieve a similar crispy, flattened result.
Can I use other vegetables?
Absolutely. Feel free to swap in eggplant, mushrooms, or even roasted tomatoes. Just make sure to slice them thin so they cook evenly.
Is this recipe vegan?
No, it contains mozzarella and pesto (which typically includes Parmesan). To make it vegan, use a dairy‑free cheese and a vegan pesto.
