Here are the ingredients: Penne Pasta, Olive Oil, Chicken Broth, Pepper, Salt, Tomato sauce, Chicken breasts, Basil, Parsley, Onion, and Garlic, I forgot to put in the picture Heavy Cream. (And on thepioneerwoman website she uses Shrimp instead of chicken, I only had chicken, so that's what you're getting. :))
After the garlic and onion have cooked a bit add your chicken stock. Let it evaporate for a few minutes, stirring occasionally.
