1 can Cream Of Mushroom Soup (10 Ounce Can)
1 container Sour Cream (8 Ounce Size)
1 whole Rotisserie Chicken
1 container French-fried Onions (6 Ounce Can)
When Rice-A-Roni is done, add the can of soup and the sour cream, and stir to combine. Add the chicken and mix together. Spread mixture into a sprayed baking dish (9-by-13-inch pan), but you can use what you like for how thick you want it to be) and bake, uncovered, at 350 F for 40 minutes.
Remove from oven, cover with the french-friend onions and bake for 5 more minutes. Remove from oven and try not to eat the whole thing.
