1Heat oven to 375°F. Separate dough into 8 biscuits; place biscuits 2 inches apart on ungreased cookie sheet. Bake at 375°F. for 10 minutes. Remove from oven; sprinkle with Parmesan cheese. Bake an additional 2 to 5 minutes or until golden brown.
2Split each biscuit; fill with desired fillings. (Each sandwich can be different to suit child's taste.) Arrange sandwiches, sides touching, on serving platter in wavy line resembling worm.
3Place pickles and sliced green olive on end sandwich to resemble "eyes" and sliced ripe olive for "eyebrows" and "nose." Use carrot stick for "feelers" and ketchup for mouth.
