Spinach Chicken Pasta

Okay, this is going to taste familiar to you. It's just another twist on the combination of chicken, pasta, spinach, and tomatoes. But it's easy and good.

Saute 2 onions and 2 (or more) cloves of minced garlic in 1 Tbsp olive oil.
Add 2-4 boneless, skinless chicken breasts that have been cut into approx. 1" cubes or larger.

When chicken is almost done, add:
1 pkg frozen, chopped spinach
1 (28 oz) can diced tomatoes, undrained
basil, oregano, thyme and chili pepper to taste
salt and pepper to taste

Let simmer until sauce is reduced a bit. It will still be somewhat watery, but just serve lots of garlic bread for soaking it up.
Serve over spaghetti or pasta of your choice.
