For the venison, try some taco seasoning or some Italian seasonings (basil, thyme, oregano and fennel seed). You will have instant meat for Mexican and Italian dishes. It is really tasty.
I canned a LOT of tuna this fall. My favorite recipe was the simplest.Per 1/2 pint jar, 1/4 tsp of pickling salt and 1/4 tsp of fresh ground black peppercorn. Double it up for pints. Pack it tight up to your mark. The meat has tons of water and oil in it, so no need for additional broth unless you want the flavor.
This also works really good with salmon. To make it even better, throw the salmon in the smoker for 45 minutes or so, take the skin off, chunk up, and can just like the tuna. Never tried smoking the tuna. Hmmmm
