Step 1

Heat a large skillet over medium high heat. Add the olive oil, onion, and pepper, sprinkle with ¼ teaspoon salt, and cook until just softened, about 3 minutes, stirring frequently.

Step 2

Add the ground beef, sprinkle with ¼ teaspoon salt, and cook until browned and just cooked through, about 5 minutes. Add the beef stock and stir to get any browned bits from the bottom of the pan.

Step 3

Carefully transfer the cooked beef and onion mixture to a 6-quart slow cooker. Add the beans, tomato sauce, diced tomatoes, garlic powder, cumin, paprika, chili powder, sugar, and 1 teaspoon salt, stirring to combine.

Step 4

Cover and cook on high for 3-5 hours, or low for 5-7, or until the beef is very tender.

Step 5

Taste and adjust seasons as desired and serve with optional toppings.
