Spinach and Feta Pasta

1 (8 ounce) package penne pasta

2 tablespoons olive oil

1/2 cup chopped onion

1 clove garlic, minced

1 jar (14.5 ounces) diced tomatoes

2 cups spinach leaves, packed (I just used frozen and it worked fine)

salt and pepper to taste

1 pinch red pepper flakes

feta cheese, crumbled

While boiling your pasta, heat olive oil in a large skillet over medium-high heat; add onion and garlic, and cook until golden brown. Mix in tomatoes and spinach. Season with salt, pepper, and red pepper flakes. Cook 2 minutes more, until tomatoes are heated through and spinach is wilted.

Prepare your plate and top with feta cheese. You can use as little or as much as you want.

It was sooooooooo good!!!
