Step‑by‑Step Instructions for Grilled Veggie & Mozzarella Sandwiches
Step 1: Prepare the Grill
Preheat your grill or grill pan over medium-high heat for about 5-10 minutes to ensure it’s nice and hot. You want the surface to be sizzling when you place the veggies on it. This step is crucial for achieving those beautiful grill marks and locking in flavors for your Grilled Veggie & Mozzarella Sandwiches.
Step 2: Vegetable Prep
Wash and slice your zucchini, eggplant, and red bell pepper into uniform pieces, about half an inch thick. In a mixing bowl, toss these vegetables with olive oil, balsamic vinegar, salt, and pepper, coating them evenly. This marinade will enhance the flavors and help the veggies become tender and delicious when grilled.
Step 3: Grill Veggies
Place the marinated vegetables directly onto the grill and cook for about 3-4 minutes per side. Keep an eye out for nice grill marks and tenderness; you want them to be slightly charred and beautifully caramelized, adding smoky flavors to your Grilled Veggie & Mozzarella Sandwiches. Once finished, remove them from the grill and set aside.
Step 4: Assemble Sandwiches
Take your rustic sourdough bread slices and spread pesto on one side of each slice, if you’re using it. Layer the grilled veggies generously, followed by slices of fresh mozzarella cheese. Feel free to mix and match with any leftover veggies you enjoy for an even more customizable experience.
Step 5: Grill Sandwiches
Brush the outside of each assembled sandwich with olive oil to achieve a golden crust. Grill them on medium heat for about 3-4 minutes per side, or until the bread is crispy and golden, and the mozzarella is melted. Press down gently with a spatula to ensure even grilling—your Grilled Veggie & Mozzarella Sandwiches will be deliciously gooey inside!
Step 6: Rest & Serve
Once grilled, let the sandwiches rest for a minute before slicing them in half. This brief resting period allows the gooey mozzarella to set slightly. Serve warm and watch them disappear quickly—your friends and family will love the flavor-packed goodness of these Grilled Veggie & Mozzarella Sandwiches!

Expert Tips for Grilled Veggie & Mozzarella Sandwiches
Preheat the Grill: Make sure your grill is properly preheated to lock in flavors and moisture, resulting in perfectly grilled veggies.
Even Slicing: Cut your vegetables into uniform sizes to ensure they grill evenly—this will prevent some pieces from becoming mushy while others remain raw.
Don’t Overcrowd: Give your veggies enough space on the grill; overcrowding leads to steaming instead of that beautiful char we love for the Grilled Veggie & Mozzarella Sandwiches.
Watch the Bread: Keep a close eye on the sandwiches while grilling to prevent burning—adjust the heat if necessary for that golden-brown perfection.
Layer Wisely: For added depth, layer different cheeses or spices in your sandwich. This opens up endless customization possibilities while keeping it delicious!
How to Store and Freeze Grilled Veggie & Mozzarella Sandwich
Fridge: Store unopened Grilled Veggie & Mozzarella Sandwiches in an airtight container for up to 3 days to retain freshness and flavor.
Freezer: For longer storage, wrap sandwiches tightly in plastic wrap and then in aluminum foil before freezing. They can last up to 2 months and maintain quality.
Reheating: To reheat, thaw in the fridge overnight, then warm in a skillet or grill pan over medium heat for 5-7 minutes, allowing the cheese to melt and the bread to crisp.
Make-Ahead Tips: Assemble sandwiches without grilling and store them wrapped in the fridge; grill them just before serving for the best taste and texture.
