Heat oven to 375°F. Lightly spray 10 regular-size muffin cups with cooking spray.
Separate dough into 10 biscuits. Press each in bottom and up side of muffin cup.
Heat 10-inch skillet over medium heat. Add beef; cook 8 to 10 minutes, stirring occasionally, until thoroughly cooked. Drain, discarding any excess fat. Stir in barbecue sauce, ketchup and mustard. Spoon rounded tablespoon beef mixture into each dough-lined muffin cup.
Top each cup with 3 potato nuggets; sprinkle each with cheese.
Bake 15 to 20 minutes or until potato nuggets and biscuit cups are golden brown.
