Step 1: Preheat your oven to 400°F (200°C). If using a pizza stone, place it in the oven to preheat.
Step 2: Lightly brush one side of each flatbread with olive oil. This helps achieve a crispier crust.
Step 3: Place the oiled side down on a baking sheet, pizza stone, or directly on the oven rack (if using a sturdy flatbread).
Step 4: Spread about 2 tablespoons of your chosen sauce evenly over each flatbread, leaving a small border for the crust.
Step 5: Sprinkle about 1/4 cup of mozzarella cheese over the sauce on each flatbread.
Step 6: Distribute your chosen protein and vegetables evenly among the four flatbreads. Don't overload them, or they might become soggy.
Step 7: Top with the remaining mozzarella cheese.
Step 8: Bake for 12-15 minutes, or until the cheese is bubbly and golden brown, and the crust is crispy. Keep an eye on them as oven temperatures can vary.
Step 9: Carefully remove the flatbread pizzas from the oven. Let them cool for a minute or two before slicing and serving. Garnish with fresh basil or red pepper flakes if desired.
