Here's ours:

1# of either ground bison or ground lamb, browned and drained of excess fat
mashed potatoes
canned green beans
canned corn
some sort of smoked cheddar
cream of mushroom soup

Layer in a glass baking dish like so:

meat
soup
green beans
potatoes
corn
cheese

Bake until nice and bubbling and the cheese has started to brown up.

Enjoy!
