In a large soup pot, heat the olive oil at medium-high heat. Add the onion and green pepper, and stir for about 3-4 minutes until it begins to soften.
Add the ground beef and ground Italian sausage. Season with salt and pepper. Stir continuously until meat is browned.
Add all the spices, diced tomatoes, and tomato paste, and stir together until thoroughly combined. Add 1-2 cups of water depending on desired thickness.
Bring to a boil, reduce heat to low, cover and simmer 40-45 minutes, stirring occasionally. Check seasoning.
Top each bowl with half of a chopped avocado and serve.
Garnish with Keto Crisps, cheddar cheese, sour cream, green onions, cilantro, or jalapeños, if desired.
