Making Delicious Spinach Tomato Pasta is straightforward. Just follow these steps:

1. Cook Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve ½ cup pasta water before draining.

2. Saute Garlic: In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute or until fragrant, being careful not to burn it.

3. Add Tomatoes: Pour in the can of diced tomatoes (with juices) and bring to a simmer. Stir in the oregano, salt, black pepper, and red pepper flakes if using. Let cook for 5 minutes.

4. Add Spinach: Stir in the chopped spinach and cook for an additional 2-3 minutes, or until wilted and tender.

5. Combine Pasta and Sauce: Add drained pasta to the skillet, tossing to combine with the sauce. If the sauce is too thick, add reserved pasta water, a few tablespoons at a time, until reaching the desired consistency.

6. Serve: Remove from heat and adjust seasoning if necessary. Serve warm, topped with grated Parmesan cheese and fresh basil for garnish.
