Elise has a great Beef Stroganoff recipe on her Simply Recipes site. It is such a popular recipe with kids, and I serve over rice and chips. If you do not want to make the Beef Stroganoff, try the substitute I mentioned below.
Stroganoff Beef Cups
12 slices of bread (you can use wholewheat bread)
3 tablespoons softened butter
Beef stroganoff leftovers
¾ cup shredded Cheddar cheese
Salt and pepper to taste
Preheat oven to 350°F (180°C). Butter one side of each slice of bread and press each one butter-side down into the cups of a muffin tin. Fill each bread cup with the stroganoff or the cooked ground beef mixture below. Sprinkle shredded Cheddar cheese over the tops. Bake for 15 minutes.
Substitute stroganoff: cook 1 pound ground beef, 1 small onion. Add one can condensed cream of mushroom soup (or heavy cream), salt and pepper to taste, combine and fill the bread cups, sprinkle cheese on top, and bake 15 minutes. Serve with potato chips on top.
