I often make it ahead and stick 4 in the freezer and cook 4 that night.
It's very easy to adapt and don't tell my husband, but I often use up leftovers this way...... you can only serve them so many times before they start getting tired of them, but add a little rice and another spice and stick it in a pepper........... TA-DA - new dish! :-)
4-8 peppers, tops cut off, seeds removed
(I can only get 4 peppers in my crockpot at a time......... and it's just me and my husband and 3 small kids so we usually do one for each adult and the kids all split one and one left for husband's lunch the next day!)
1 pound ground beef, browned
2 cups cooked rice or barley
1 cup corn (usually frozen.....!)
1 can diced tomatoes
3-4 cloves garlic, minced
1 cup cheese, grated
1 tsp salt
1/2 tsp pepper
1-2 tsp oregano, basil or cilantro
1 tsp chili powder
1 tsp cumin
Mix everything together well and spoon into peppers, I sometimes replace the tops and often don't - chopping the tops and throwing into a salad!
Place in crockpot and cook on low 4-6 hours - till pepper is desired tenderness.
Can place in crockpot frozen........ increase cook time a couple hours.
Like I said, I often make this "cleaning out the refrigerator" - I might mix some sausage gravy, rice and zucchini......... chicken soup trying not to get too much broth......... chicken, rice and brocoli casserole........... the possibilities are endless and make for a wonderful "re-use" of food and the ease of the crockpot! Obviously, please adjust the spices and such to your taste and what combinations of food you are using!
