1 (10 ounce) can diced tomatoes and green chiles (such as RO*TEL®)
1 (3.8 ounce) can sliced black olives, drained
2 tablespoons ranch dressing mix (such as Hidden Valley Ranch®)

Combine ground beef, onion, and jalapeno in a 4-quart soup pot and cook over medium-high heat until beef is cooked through and no longer pink, about 5 minutes.
Add crushed tomatoes, pinto beans, water, corn, black beans, diced tomatoes and green chiles, black olives, ranch dressing, and taco seasoning. Mix to combine. Bring soup to a boil, reduce heat, and simmer for 30 minutes.
