A good friend brought us venison but you could do this with beef or ground turkey if you wanted!
First I chopped half an onion and 3 mushrooms. Saute until cooked through and set aside. Add a handful of cheddar cheese!
I seasoned the meat in a bowl with garlic, onion, salt, and cumin. Just a general sprinkle of each and then mix well (I used my hands).
Form into a patty and set on a clean surface (I put down aluminum foil to keep my counter clean) Do this for as many people as you are serving (I used 2lbs of meat for 4 people...but these are HUGE burgers so you could easily share) Use half of the meat for this step.
Put a spoonful of the veggie mix in the center of the patties. Take what meat is left and form a patty and place it on TOP of the patty with the mixture so the mix is inside. Press to seal the edges.
Cook in a hot pan! I found that putting a lid on helped it cook a bit more evenly. You'll want to cook over lower heat because these are THICK and take longer to cook through.
I did cheese on top as well. :)
