Take the roll dough and unroll them carefully. Cut each triangle in half. (will need part of the second box; but not all) ; keeping the triangular shape. Then wrap 1/3 or a piece of cheese around the frank and holding it with your fingers start rolling it in the roll. Start at the large end of the triangle and roll towards the tip. Bake in a hot oven until brown...should only take about 10 minutes at 400 degrees. Watch carefully. Take out when they are browned. Serve immediately.
