I don't know how ya'll mix or grind your venison, but we do a lot of it without adding any pork fat or high-fat beef, so I do have a lot of lean venison packed that I modify when I cook if needed.

A couple weeks ago, I made Vension slider burgers with some venison & egg to hold them together. I had little leftover from the slider burgers, so I cooked up the remainder for tacos the next night, along with some beef since I didnt have enough venison-only for taco Tuesday.

Well.... This sure shows the difference between a good quality Venison and just your standard lean beef. I didnt oil the pan enough, so I even had to add some of the beef to the venison to get a little grease action.
