In a skillet over medium heat, brown ground beef until it is no longer pink, and drain excess grease if needed.
Add ground beef, smoked sausage, beans, corn, potatoes, fire-roasted tomatoes, tomatoes with green chilies, beef broth, and chili seasoning to 6-quart slow cooker, and stir well.
Cover and cook on low for 6-7 hours or high for 3-4 hours, until potatoes (if using fresh) are tender and flavors are blended.
Stir, taste, and adjust seasoning if needed before serving.
