CORN Salsa: Combine ingredients. Refrigerate until ready to serve.
MEATLOAF: MIX first 6 ingredients and 1-2/3 cups barbecue sauce (or 1/3 cup barbecue sauce for trial recipe) until blended. Portion 6-1/2 oz. into each of 50 greased 4-1/2-inch muffin cups (or into each of 10 muffin cups for trial recipe). Bake in 300ºF-convection oven 20 min.
CHEESY Mashed Potatoes: Meanwhile, boil potatoes 15 min. or until tender; drain.
