Add the sausage, onion, and celery to the pot. Cook until the onions have softened. Mix in the jalapeño and garlic and cook for an additional minute. Drain off any excess grease. Stir in the ground beef, beef broth, potatoes, mixed vegetables, pinto beans, diced tomatoes and green chilies, tomato paste, chili powder, Italian seasoning, smoked paprika, salt, and pepper. Bring the mixture to a boil, then reduce the heat to a simmer. Continue to cook until the potatoes are tender, about 40 to 45 minutes.
