Dr. Osborne himself suggests mashed potatoes as a substitute for bread crumbs. I used 1 cup instant mashed potatoes in a recipe that uses 2 pounds of beef. The mashed potatoes will soak up some of the flavor from your spices, so you might want to either use less mashed potatoes, or increase your spice amounts a little bit. By the way, I also use smoked paprika and chili pepper in my recipe. Oh, yeah!! Adding some of your favorite BBQ sauce is not a bad idea, either.
