Add vinegar to skillet. As the liquid sizzles, scrape up any brown pieces that are stuck to the bottom of the pan. Vinegar will help decrease any gamy flavor.
Add meat mixture to slow-cooker with all other ingredients except spinach.
Stir to combine
Cook on LOW 6-8 hrs
After chili has cooked, stir in spinach and allow it to wilt
Recipe Notes
*I usually use game meat but will use beef if that is not available.
I sometimes add the left-over zucchini scraps from making zoodles or any other vegetables that are looking a little wilted in my fridge. To this day I have not found a vegetable that has not tasted great in this chili. If you find one, please let me know!
