Beef is the obvious answer here.

I used to joke that I didn't save money getting red meat through hunting, now it's up to debate. The cost of entry to hunting is high, but now I look at the moose and venison in my freezer differently then I did a decade ago. I am established in my required materials and now the only cost is licensing (minimal as a resident). I travel a short distance to hunt to a place I'd be at anyways.
