Yesterday, I had a marvelous roast beef. So… today is leftover day and I always have stuffed peppers.
Cut up the roast in pieces small enough to fit in your processor, add the potatoes, carrots, onions, celery and anything else that you cooked with the roast, process it for a very short while until everything is small but distinguishable as individual food. Then you mix in the leftover gravy and stuff the peppers until they are overflowing. Bake in a 350 deg. oven until peppers are totally done and everything is bubbly. Server with cheesy garlic bread and you are set.
