You might want to check out this online database of recipes:
http://www.nativetech.org/recipes/index.php
The database can be searched various ways, including by region, by type of dish, and whether a dish uses only indigenous ingredients or if it is a more contemporary sort of adaptation.
Warning: some of these dishes may be
too authentic for the cooking club.

(ones with moose, prairie dog, a stew made with crow brains...)
More realistic options would probably be:
fry bread
corn, beans, squash/pumpkin (known as the
three sisters by the Iroquois)
maybe something with
wild rice
a stew of venison, if you can get it, or rabbit, or turkey
for dessert, probably just berries. Or something sweetened with maple syrup.
Good luck!
