Okay, came up with another good one tonight...
leftover roast chicken, cut up into pieces
1 onion chopped
2 stalks celery chopped
3 large carrots chopped
leftover mashed potatoes
package of powered cheese from a mac-n-cheese box
1 cup chicken broth
in a deep pie-dish add:
chopped cooked chicken
in a pot, mix chicken broth, potatoes & powdered cheese until the consistency of pancake batter (i had frozen chopped red pepper and fresh green onions and added it for color)
ADDED: hubby says that the chopped red pepper and green onions are a must, otherwise it's too bland. so, make sure you chop and freeze some raw red sweet bell peppers this summer when they're wicked cheap)
take a scoop of the potato mixture and add a splash of milk, pour onto the chicken/veggie mixture (for a sauce)
pour the rest of the potato mixture over the chicken/veggie mixture and bake
bake for 30 - 45 min at 375 (or less time at higher heat, check to make sure not burning)
you could cheat and use cream soups for this, but i didn't have any, which is why i made the sauce the way i did.
