Walden Farms make a sugarfree ketchup. If your local grocer has a diabetic section...look there, that's where I found it.
For the shake and bake, I suggest using the original style Fiber One cereal...someone else chime in, but I'm pretty sure that kind is okay for SBD. It's the kind that looks like little noodles....put them in a food processor or crush them up somehow to a powderlike consistancy. Then blend in some different herbs/spices so that the "cereal taste" goes away

) other wise it'll taste like chicken dipped in cereal

This also works for home made onion rings...yum...I usually put lots of garlice powder in my mixture....then whatever other herbs/spices you like...ceyenne pepper? oregano? whatever.
