Preheat oven to 350�F. Set out a baking sheet. Mix cheese and butter till well blended. Stir in flour and salt and mix well. Add Rice Krispies and work in by hand. Divide dough into half, then cut each half into 15 pieces. Roll each piece into a ball, placing on baking sheet, and flatten with a fork. Bake in preheated 350�F oven for about 10 minutes. Makes at least 30 snacks. Store in a sealed container (like empty coffee can). From Ethel Meyers
