This recipe was found accidentally. It started out as a pizza topping. Didn't want to take time to make the dough so I thought I'd just make the topping. Turned out fantastic, in my opinion. Very easy, very fast, and very tasty
Place the olive oil in a large frying pan and heat over medium heat. Add chicken, cook and stir for 2 minutes. Add onion and pesto; cook and stir for about 4 minutes or until chicken is cooked through. Stir in tomatoes and cheese. Let cool slightly before serving.
