I love a good casserole and this is a good one to add to the list! Gray loved it as well! I found the recipe over at Just Cook Already, and adapted it a bit. It's a winner, try it, you will be surprised by the flavor the poppy seeds give it!
4 chicken breasts, skinless and boneless
1 16 oz container sour cream
1 can cream of chicken soup
1 can cream of mushroom soup or cream of celery soup
1 sleeve snack crackers, crushed
2 tsp poppy seed
1/2 cup butter, melted
Boil and shred the chicken. Mix together sour cream, chicken soup, cream of mushroom (or celery) and poppy seeds. Add chicken, mix and pour into a casserole dish. Sprinkle crush crackers on top then spread the melted butter on top! Bake at 350 for 25 minutes!
