Y'all have got to try this stuff.
2 cups cooked rice
2 cups cooked, diced chicken
2 cans cream of mushroom soup (cr celery or cr chicken also ok)
1 cup sour cream
1/2 large red pepper
2-3 green onions
1 medium onion, diced (feel free to adjust vegetables to suit yourself)
2 cups sliced mushrooms
1/2 cup finely chopped celery
2 cups shredded cheddar
2 cups crushed nacho cheese tortilla chips
spread the rice in the bottom of a 9x13 dish. Mix the chicken, soup, sour cream and vegetables in a bowl and pour over. Top with cheese, bake at 350 for 35 minutes. Sprinkle chips, bake 5 minutes more. Makes quite a lot of food, be prepared to eat leftovers.
