Precook chicken breasts in boiling water until thoroughly cooked. Remove breasts from water and let cool (save the broth for other things!)
Tear cooled breasts into bite sized pieces, and put in bottom of casserole dish.
Mix together sour cream, cream of chicken soup and cream of mushroom (or cream of celery) soup and spread on top of chicken. Cover with crushed snack crackers. Sprinkle poppy seed on top. Drizzle melted butter on top.
Place in preheated 350°F oven until warmed through, about 20-25 minutes.
Enjoy!
