Separate and place frozen roll dough on cookie sheet. Let thaw and rise.
Take 3 slices of pepperoni and place in middle of one roll, smush down and wrap dough around pepperoni. Continue till all balls of dough are filled. Let rise again.
Bake at 350 for approx. 9 min. or until rolls are light golden brown. Don't overbake.
Take stick of margarine and rub it over top of hot rolls immediately after they are removed from the oven.
Serve immediately. They can be reheated in the microwave or eaten cool. They never last long enough to be frozen.
