Heat oven to 375°F. In 2-quart saucepan, cook macaroni as directed on package.
Meanwhile, separate dough into 10 biscuits. Press 1 biscuit in each of 10 ungreased regular-size muffin cups, firmly pressing dough to cover bottom and side, forming 1/4-inch rim over edge of cup.
Drain macaroni; return to saucepan. Stir in cheese dip and roasted peppers until macaroni is coated. Spoon about 1/4 cup macaroni mixture into each cup.
Bake 14 to 18 minutes or until edges of biscuits are golden brown.
