1Heat oven to 375°F. Spray 24 mini muffin cups with cooking spray. Unroll dough on work surface. Press into 12x8-inch rectangle. (If using crescent roll dough, firmly press perforations to seal.) With pizza cutter or sharp knife, cut into 6 rows by 4 rows to make 24 squares. Press 1 square in bottom and up side of each muffin cup.
2In medium bowl, mix mashed potatoes, cream cheese spread and pepper with spoon or electric mixer on medium speed until smooth. Stir in ham, 2 tablespoons of the green onions, the Cheddar cheese and bacon until combined. Spoon potato mixture into cups.
3Bake 15 to 17 minutes or until golden brown. Cool in pan 2 minutes. Using metal spatula or small knife, run around edges of cups to loosen, and remove from pan to serving platter. Top with remaining 2 tablespoons green onions. Serve warm.
