These are sold at all grocery stores that carry Goya products. They also come in 'white'.
You can use a rolling pin to stretch them out a bit.
Use any pepperoni you like. I like the cubed.
Fill with cheese & pepperoni. And use some water to wet the edges to help seal it.
Use a fork to press edges
Lay on cookie sheet. And brush tops with melted butter.
Bake at 400 degrees for about 10 min or until edges are slightly brown & crisp. Enjoy:)
