For a vegetarian option, substitute the ground venison with an additional pound of finely chopped mushrooms or a plant-based ground meat alternative. Feel free to experiment with different types of mushrooms, such as cremini, shiitake, or oyster mushrooms, for unique flavor profiles. If blue cheese isn't your preference, try crumbled cotija cheese or a dollop of sour cream for a creamy alternative. To add a spicy kick, incorporate a pinch of cayenne pepper or a dash of your favorite hot sauce to the meat mixture.
