How to make Grilled Veggie Mozzarella Melts
Step 1: Prepare the grill and vegetables
Preheat grill to medium-high heat. Brush bell peppers, zucchini, and red onion with 1 tablespoon of olive oil. Season with salt and pepper.
Chef’s Tip: To prevent sticking, make sure your grill grates are clean and lightly oiled before adding the vegetables.
Step 2: Grill the vegetables
Grill the vegetables for 3-4 minutes per side, or until tender and slightly charred. Remove from grill and set aside.
Step 3: Grill the bread
Brush the ciabatta slices with the remaining olive oil. Grill for 1-2 minutes per side, or until lightly toasted.
Step 4: Assemble the sandwiches
Top 4 slices of grilled ciabatta with mozzarella slices, grilled vegetables, and a drizzle of balsamic glaze.
Step 5: Finish and serve
Place the remaining 4 slices of grilled ciabatta on top to create sandwiches. Serve immediately, garnished with fresh basil leaves if desired.

Frequently Asked Questions
Can I use different vegetables?
Absolutely! Feel free to use other vegetables like eggplant, mushrooms, or asparagus. Just adjust the grilling time accordingly.
