Instead of bread crumbs in the meat loaf, my mother always used saltine crackers.
I use an 8 ounce bag of TGIF cheddar/bacon potato skin chips crushed to a pulp. I used ketchup in the mixing bowl, some DICED green pepper, and some diced onion. I don't use any other seasoning.
And since I am OFF potatoes, I add a drained can of corn kernels to bake with the loaf.
And when it comes out of the oven, I add a ketchup glaze to the top.
