Cook the bacon using low-medium heat. As it’s about to finish, mix in the onion, salt it a bit, and then add the mushrooms once the onion goes soft.
When the mushrooms start browning, heat up the skillet to medium and add the ground beef to this. Cook until the meat is nice and brown. Afterwards, you should combine the salt, cumin, chili powder, and oregano. Stir for one minute.
You can add the paprika or cayenne if you think the chili isn’t spicy enough. When it’s so hot it burns your tongue off, you then go back to low-medium and add the tomato paste. Stir it in until everything is darkened.
Combine the broth and wine, stir, simmer, and do this for about 10 minutes, until the sauce thickens. Combine any other spices if it’s not up to taste. Afterwards, you combine the wine vinegar, then serve.
Pro Tip: You can also garnish this chili with cheese, avocado, sour cream, jalapenos, or anything else that has low carbs in it.
