Creating One-Pot Pizza Pasta is simple and requires just a few steps. Follow these instructions for a delicious meal:

1. Heat Olive Oil: In a large pot, heat the olive oil over medium heat.
2. Sauté Vegetables: Add the diced onion, bell pepper, and minced garlic. Sauté for about 3-4 minutes until the vegetables are soft.

7. Season to Taste: Add salt and pepper according to your preference.
8. Serve: Remove from heat and sprinkle the remaining mozzarella cheese on top. Cover for a few minutes to allow the cheese to melt further.
9. Garnish: Serve hot, garnished with fresh basil if desired.
