In a medium-sized pot over medium-high heat, cook bacon until very crispy. Roughly chop bacon and set aside.
Cook together ground beef, Italian sausage, bell pepper, celery, onion, garlic, and jalapeno until cooked through. Drain grease from meat and vegetable mixture.
Once drained, add in diced and crushed tomatoes, vegetable broth, chili seasoning, and salt and pepper. Mix well and bring chili to a boil.
Once boiling, simmer for 20-30 minutes.
Once ready to serve, stir in bacon and, one handful at a time, cheese until fully incorporated. Garnish with crumbled bacon, avocado, cheese, and sour cream.
