1. Combine butter, lemon juice, brown sugar, honey, soy sauce, ginger, and cloves in a 2-cup glass measure. Microwave at Time Cook (power level 10) for 1 minutes, or until brown sugar is melted, stirring twice.
2. Thread ham, pineapple, and banana alternately on four 9-inch skewers. (Use wooden skewers if possible, though metal ones may also be used.) Arrange kabobs in a 13" x 9" x 2" oblong baking dish. Brush with the butter sauce. Microwave at Time Cook (power level 10) for 6 minutes, or until heated through, turning the skewers and basting with remaining butter sauce after 3 minutes.
