I using dinner rolls, cut each roll in half and place on a sprayed baking sheet, cut side down. Cover with sprayed plastic wrap and let rise until double in size; remove plastic wrap.
For all rolls, carefully brush with butter. Sprinkle Asiago cheese on the top of each roll and season with garlic salt.
For dinner rolls, bake at 350°F 10-12 minutes or until golden brown.
For Warm-N-Serv® follow directions on package. Cool and slice each roll almost all the way through.
Spread the inside with mayo and mustard. Fill each roll with a slice of turkey and a half slice of cheese. Secure each filled roll with a tooth pick, if desired.
