Heat oven to 375 degrees
Cut cheddar cheese & jalapenos into thin, skinny slices (for ours I like the slices about ¼” thick and 2” long)
Unroll the cans of crescent rolls and cut each triangle into two.
Place sausage, cheese, jalapeno in the shortest edges of the triangles and roll up your pigs in a blanket.
Place pigs in a blanket on an un-greased baking sheet
Optional: brush the tops with egg and sprinkle with pretzel salt
Bake for 12 - 15 minutes, or until the tops turn golden brown
