Cut each jalapeno in half lengthwise; remove seeds and stems. Stuff each pepper half with about 1 tablespoon cheddar cheese. In a bowl, combine the uncooked sausage, biscuit mix and remaining cheese; mix well. Shape about 2 tablespoonfuls around each pepper.
Dip into eggs, then roll in coating mix. Place on a baking sheet coated with cooking spray. Bake at 350° for 35-40 minutes or until golden brown.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
