Thaw and let rise in warm spot (about an hour) .
Once thawed, flatten in your hand and place pepperoni inside. Stick or per-sliced pepperoni will work. I think stick pepperoni is the best. Fold dough around pepperoni, place seam down on baking sheet.
Cover with clean towel and let rise again ( 30 minutes) .
Bake 350 degrees for 15 minute or until the top of rolls are brown and bottoms look orange.
Rub a little butter on the tops and serve. Yummy !
