This is really simple, but I've gotten more requests for this recipe than any other I've made.

2 lg. cans baked beans
1/2 c. catsup
1 tbsp. mustard
1/3 c. brown sugar

Open baked beans, put in large saucepan. Add catsup, mustard and brown sugar. Cook over medium heat until mixture becomes bubbly. Stir occasionally to keep from sticking. Serve warm. Great for barbecues!
