This is actually going to call for you to have a few ingredients on hand, but what the heck:
This is one of my family's favorites (although I make the meatballs myself, but you can use frozen packaged ones if you like). I make a sweet-sour sauce using the following:
1 can condensed tomato soup (do NOT add water)
2 tablespoons of prepared mustard
2 tablespoons of brown sugar
2 tablespoons of Worchestershire sauce
Combine all the ingredients in a saucepan over medium-low heat until the brown sugar is dissolved. Add meatballs to the sauce and increase the heat to medium to medium-high and simmer until cooked through.
This sauce is also excellent on chicken wings: Heat the oven to 375F, and brush the sauce over the wings, let cook for 20 minutes. Then turn the wings, brush sauce on the other side, and return to oven for another 20 minutes.
I always serve either of these dishes with rice cooked in the microwave: 2 cups hot water for 1 cup of parboiled white rice, microwaved on high for 20 minutes. We use any extra sauce as a topping for the rice too.
Serve with salad on the side. (I buy the bagged, pre-made salad. I admit it: I just hate making salad and this is the only way I'll have salad.)
An alternate recipe for meatballs:
1 can condensed tomato soup
1 package onion soup mix
1 can sliced mushrooms (or use fresh if you're feeling energetic)
only add enough water to achieve a smooth consistency to the sauce
Combine the ingredients in a saucepan and simmer with meatballs as described above. Serve with rice or mashed potatoes and a serving of vegetables.
