Last night the cooking club on campus that I participate in was having a meeting/potluck, and I needed something to bring. It had to be fast, easy, and delicious, of course. But since this potluck was taking place on campus in a classroom with no way to reheat food, there were the added challenges that it needed to be reasonably easy to transport, and it needed to taste good cold. Usually when I go to these potlucks, I just make cookies. This time, though, I wanted to bring something savory rather than something sweet. These little  sausage rolls fit the bill very nicely indeed, and would make a great appetizer for a party.

1 sheet of store bought frozen puff pastry (although if you like making your own, go for it!)
1/2 cup provalone cheese, grated
1/2 cup cheddar cheese, grated
1 andouille sausage, sliced into 12 pieces.

Preheat the oven to 400 degrees. Thaw the puff pastry at room temperature for about half an hour, until it is pliable. Roll it out into a rectangle about 1/8 inch thick, and cut it into 12 triangles of equal size. Put a piece of sausage in the middle of each triangle, and sprinkle the cheeses on top. Fold the two skinny ends of the triangle over the middle to cover the sausage. Moisten the ends of the puff pastry with a little water and press them together so that they will stay in place. Now place the sausage rolls on a cookie sheet and  bake for about 10 minutes, until the cheese is melted and the puff pastry is golden.
