Preheat oven to 350 degrees and spray a 13x9 baking dish with cooking spray. Set aside until ready to use.
Heat a large skillet over medium-high heat and add venison, stirring to break up pieces, until well-browned.
Add in the chili powder through the salt and stir to coat the meat. Then add in the pinto beans and stir again.
To assemble the burritos, take a tortilla and put about 1/4 cup of filling in the center and top with about 1/4 cup of shredded cheese. Then bring the sides of the tortilla in, and roll from the bottom up, into a burrito, and place in the prepared baking dish. Repeat with the remaining tortillas and filling, and then top with the sauce. I kept a little of the sauce for dipping when they were done....you can do that, or pour it all on!
Bake, uncovered, for 10-15 minutes to heat through and melt cheese. Serve immediately, with reserved sauce - if you saved any.
