Preheat oven to 200°C (400°F) and line a baking sheet with parchment paper.
Roll out pizza dough on a clean surface.
Cut dough into 16 small squares or circles.
Place dough pieces on the baking sheet.
Leave small space between each dough piece to allow proper expansion.
Spread a small amount of pizza sauce on each piece.
Sprinkle mozzarella cheese evenly over each bite.
Add bell peppers, red onion, mushrooms, and olives on top.
Drizzle lightly with olive oil and sprinkle Italian seasoning and salt.
Bake for 15–18 minutes until dough is golden and cheese is melted.
Remove from oven and garnish with fresh basil or parsley.
