Heat the avocado oil in a large heavy bottomed pot or dutch oven over medium heat. Once the oil is hot, add the ground beef and cook until brown, breaking it up as it cooks.
Next, add the minced garlic, diced onion & pepper, salt, and spices, to the ground beef and cook until the onion begins to become tender.
Add the diced sweet potatoes, beef broth, diced tomatoes, and black beans to the pot. Stir until well combined.
Bring the chili to a boil and then reduce the heat to low. Let the chili simmer for 20-30 minutes, until the sweet potatoes are tender.
Serve with your favorite toppings like green onion onion, sour cream, avocado, shredded cheddar, sliced jalapeño, and cilantro.
