Cook the burgers halfway then put them in a casserole dish. Sautee 1 onion with garlic and butter put over top of burgers, sprinkle with more garlic, bottle of ketchup with a little Worcestershire sauce, cover and bake for a while. I think I was told they can go in the crock pot too. Never heard of them either but tried them last year and got the recipe. They were so easy and a hit with the family.
