Heat a 12" cast iron skillet over medium heat with 1 teaspoon of bacon fat in it. Wait until the bacon fat has melted, then add the ground meat. Cook the ground meat. Put the meat in a crockpot and set the crockpot on high.
Chop or shred the carrot, onion, mushrooms, and pepper. In the same cast iron skillet, saute the veggies and add the crushed garlic. I sauteed mine for about 3 minutes. Add them to the meat in the crockpot.
In a small mixing bowl, combine the remaining ingredients except for the quinoa. Add the sauce to the meat and vegetables and stir to combine. Stir in the quinoa.
Set the crockpot on high for 4 hours. Stir occasionally. Serve with your favorite gluten-free or grain-free bread or buns!
