Hash. Dice or slice the potatoes, an onion, and the meat of your choice (I usually use something leftover: ham, beef, corned beef, chicken, smoked sausage). Peppers if you are so inclined. Mom even got us to eating fish on fridays by chopping fish into it. All is fried to a crisp in a skillet. Serve with a salad. Yummy meal for any time of the day (break an egg per person over it if doing breakfast). (Oh, start with sauteeing any fresh vegs you're cooking with the leftovers so they will be cooked when you're through).
