Okay, the broccoli dip wouldn't get past guacamole snobs, fair enough!
I did a lot of searching and found low-sodium baking powder (Hain's) zero sodium bouillon (Herb-ox), substituted dillweed for dill pickles in tuna salad, things like that. I can give you the cookie recipe, it uses white and brown sugar Splenda, not everyone likes that. Oh, and I found a peanut butter powder, just add water! Didn't use it in the cookies but you could. Less salt and fat.
