As for breading: Some time ago it was popular to used crushed Kellogg's corn flakes as breading for chicken. Does anybody do that anymore, or was it one of those dreadful 1950's food fads?
And meatloaf.... I can't answer your question, but it reminds me of a great episode of Roseanne, when she's got Darlene's Home Ec class at the grocery store, teaching them to shop for and cook a meal for the family. Meatloaf is on the menu, and she explains how you can use cornflakes to stretch your dollar and use less meat. She sends Darlene to get a box of cornflakes and then scolds her when she returns with the name-brand, telling her to exchange it for the generic. Darlene says, "But Mom - this is what you always buy at home!" Roseanne replies, "That's what YOU think. I've been refilling that same box for 10 years."
It was funny when I saw it years ago, but sadly now, I'm living it. My kids haven't seen a Kellogg's product in 5 years.
