In a large stock pot add the a little oil over medium heat. Add all the ground meat and brown while breaking up and mixing together. Once cooked through remove and set aside. Get rid of most of the fat.
In the same pot with a little bit of the grease, add the onion, green pepper and celery. Sauté briefly until the onions are translucent. Add the Tomatoes, You can crush them as I do when I add them or just break them up as they cook with your spoon. Add the Rotel, cumin and chili powder to taste. Bring to a boil and cook the veggies for about 8-10 minutes.
Add the beans, browned meat and the chili seasoning packet. Partially cover and let this simmer for 4 hours.
Serve with shredded cheddar cheese, sour cream and chives or green onions. One of my favorite ways is for my husband to make me an omelet with chili. It is the best!
