Heat a large nonstick skillet over medium high heat. Season ground beef with salt and pepper; cook and stir in batches in the hot skillet until browned and crumbly, 5 to 7 minutes per batch. Remove meat to a colander to drain and then set aside in a large bowl. Drain and discard grease from skillet between batches.
While meat is cooking, combine stewed tomatoes, tomato paste, chili powder, sugar, and garlic salt in the bowl of a food processor; blend until smooth.
Heat olive oil in a 16 quart pot over medium high heat. Add celery, onions, green pepper, red pepper, jalapeno peppers, and garlic. Cook and stir until vegetables have softened and onion has turned translucent, 7 to 10 minutes. Add reserved meat, stewed tomato puree, and undrained light and dark red kidney beans. Simmer for 1 hour.
