In large bowl, mix sausage and cheeses until blended well. Wearing latex gloves, cut peppers in half, remove stem and seeds, drain well on paper towels. Preheat oven to 350° F. Roll sausage and cheese mixture into balls and press into jalapeno halves until slightly rounded. Bake on oven broiler pan 15 minutes, or until lightly browned. Allow to cool 5 minutes before removing from pan; serve warm.
