When making Mexican stuffed bell peppers there are many different options on what you can use to fill your bell peppers with. For instance, you can use any ground meat you have on hand, such as ground beef or ground turkey. You can substitute the ground meat and use shredded chicken, or make it vegetarian and use beans. Since we always have a freezer full of deer meat on hand, I like to incorporate deer meat into any recipe that calls for ground meat. For this recipe I use half ground beef (73% lean) and half ground deer meat.
