This is something I came up with after a tasting at a local grocery store. They were adding a dish to their hot bar and I went home and whipped this up. I used pasta but this would good with rice as well.
1Cook pasta according to directions, drain and pour into a large greased casserole dish.
2Heat olive oil in a large skillet. Sear chicken breast until just brown, they will go in the oven so don't overcook. Place your chicken breasts on top of pasta in casserole.
3In same skillet cook your onion and mushrooms until tender. Add alfredo sauce, enchilda sauce, and green chilies, mix well and let heat until bubbly. Pour your suace over the chicken breasts and pasta. Topp with cheese and bake 30 minutes or until cheese is melted and browned a little.
