Step‑by‑Step Instructions for Grilled Veggie & Mozzarella Sandwiches
Step 1: Prep the Grill
Begin by preheating your grill or grill pan to medium-high heat, around 375°F to 400°F. This ensures that your veggies achieve a lovely char while retaining their vibrant taste and nutrients. Keep a close watch as the heat rises so you can move quickly once you’re ready to grill.
Step 2: Prepare Vegetables
Wash and slice the zucchini, bell pepper, and eggplant into manageable pieces, around 1/4-inch thick for even cooking. In a mixing bowl, toss these vegetable slices with olive oil, balsamic vinegar, salt, and pepper until well-coated, allowing their natural flavors to shine in your Grilled Veggie & Mozzarella Sandwiches.
Step 3: Grill Vegetables
Place the coated vegetables on the hot grill, ensuring they’re not overcrowded to achieve the perfect brief sear. Grill for about 4-5 minutes on each side, or until tender and lightly charred, creating those delightful grill marks. Once done, set aside the vegetables to cool slightly while you prepare the sandwiches.
Step 4: Assemble Sandwiches
Grab your rustic sourdough slices and spread a layer of pesto on the inner sides if you’re using it, adding a burst of flavor. Layer the grilled veggies generously, followed by slices of fresh mozzarella cheese. Top with another piece of sourdough, pressing gently to hold everything in place as you prepare to grill.
Step 5: Grill Sandwiches
Brush the outer sides of each sandwich with olive oil to create a beautifully crisp exterior. Grill the sandwiches for about 3-4 minutes on each side until golden brown, paying attention to that lovely melting mozzarella inside. Flip carefully to maintain the integrity of the ingredients as they heat through.
Step 6: Serve
After grilling, remove the sandwiches from the heat and let them rest for a minute to firm up. Slice them in half for easy handling, and garnish with fresh basil leaves for an aromatic finish. Serve warm, and enjoy your delicious Grilled Veggie & Mozzarella Sandwiches alongside your favorite sides!
