Grilled sourdough with mozzarella, tomato, basil, and balsamic glaze for an Italian-style vegetarian sandwich.
# What you'll need:
→ Bread & Dairy
01 - 4 slices sourdough or rustic bread
02 - 4 tablespoons unsalted butter, softened
03 - 4 ounces fresh mozzarella cheese, sliced
04 - 2 tablespoons grated Parmesan cheese (optional)
→ Vegetables & Herbs
05 - 1 large ripe tomato, sliced
06 - 8 to 10 fresh basil leaves
→ Condiments
07 - 2 tablespoons balsamic glaze
08 - Salt, to taste
09 - Freshly ground black pepper, to taste
# Method:
01 - Spread softened butter evenly on one side of each slice of bread.
02 - Place two slices of bread, buttered side down, on a clean cutting board. Distribute sliced mozzarella cheese, tomato, and basil leaves evenly between both slices. Season with salt and freshly ground black pepper.
03 - Drizzle 1 tablespoon balsamic glaze over the tomatoes on each sandwich. Sprinkle grated Parmesan on top, if using.
04 - Top each with remaining bread slices, buttered side facing up.
05 - Heat a nonstick skillet over medium heat. Place sandwiches in the skillet and grill for 3 to 4 minutes per side, pressing gently with a spatula for even browning, until bread is golden and cheese is fully melted.
06 - Remove sandwiches from heat, allow them to rest for 1 minute, then slice and serve immediately while warm.
