Using the same skillet, add diced onion, red bell pepper, and minced garlic. Cook until softened and translucent, approximately 3 to 5 minutes, to enhance sweetness and flavor.

Transfer browned beef and sautéed vegetables into the slow cooker. Add kidney beans, diced tomatoes with juices, tomato sauce, beef bouillon cubes, chili powder, smoked paprika, cumin, oregano, salt, black pepper, cayenne (if using), beef broth, and lime juice. Stir thoroughly to combine.

Taste and adjust salt, heat, or acidity if necessary before serving. Serve warm, garnished with toppings such as shredded cheese, sour cream, chopped cilantro, or sliced jalapeños as desired.
