In a large pot, add the ground beef and brown. Once evenly browned and cooked, remove any excess fat
Small dice the onion and mince the garlic clove. Add to the cooked beef along with the small diced sweet potato. Cook for about five minutes or until the onion starts to soften
Once the onion is softened, add the chicken stock (Beef stock is also fine in this recipe. I tend to use more chicken stock because I make so much of it and freeze it. I always have it on hand), canned diced tomatoes, tomato sauce, canned diced green chiles, chili powder, dried oregano, and salt. Stir to combine and then cover and allow to simmer on low for 45 minutes
Remove the lid and check that the sweet potatoes are cooked. Taste and add more salt if needed. If the sweet potatoes are cooked, serve and enjoy warm. If not, cover and check back every 10 minutes until the sweet potatoes are cooked through and tender
