Heat oven to 450°F. Remove pie crust from pouch. Using rolling pin, roll crust to 15-inch diameter. With lightly floured 3-inch round cutter, cut 16 rounds from crust; discard scraps. Fit rounds into 16 (2 3/4-inch) ungreased muffin cups, pressing in gently. Generously prick crusts with fork. Bake 5 to 7 minutes or until very light golden brown. Remove from pan; cool completely.
