Ingredients
- 12 oz penne pasta
- 2 tbsp olive oil

- 14 oz canned diced tomatoes
- 3 cups fresh spinach, chopped
- 3 cups water
- 1 tsp salt
- 1/4 tsp black pepper
- 1 cup mozzarella cheese, shredded
- 1/2 cup Parmesan cheese, grated
Instructions
- Step 1: In a large deep skillet or pot, heat 2 tbsp olive oil over medium heat. Add 3 minced garlic cloves and sauté for 1 minute until fragrant but not browned.
