Hmm, is that anything like Hobo Stew? I remember hubby making that when we were visiting my family. Mom had said she had always known it as tatter tot casserole.I'm not sure on the details, like I said hubby made it, but it had tatter tots, chopped hot dogs, baked beans, onions, and some other stuff for the sauce/flavoring.If it sounds familiar I can ask the hubby for the recipe for you.
It has layers of tater tots and hamburger and other things. Popular in the midwest.
By the way, if you have any other good casserole dishes let me know - I am sick of same old stuff.
