You'd have to have a knife and a deep fryer. The box just calls for "a breading mix," so you could use any commercial mix like McCormick's, or if you do a search on "breading mix," you'll find lots of recipes. The recipes included are for salsa and a couple of dips. Personally, I wonder if one could do this with baking instead of frying. The main thing you're getting here is the guide to cut the onion without taking all day.
