Ingredients

2 pounds ground beef
2 cups diced onions
2 (15 1/2-ounce) cans pinto beans
1 (15 1/2-ounce) can pink kidney beans
1 (15 1/4-ounce) can whole kernel corn, drained
1 (14 1/2-ounce) can Mexican-style stewed tomatoes
1 (14 1/2-ounce) can diced tomatoes
1 (4.6-ounce) can black olives, drained and sliced, optional
1 (1 1/4-ounce) package taco seasoning mix
1 (1-ounce) package ranch salad dressing mix

Directions

Brown the ground beef and onions in a large skillet; drain the excess fat, then transfer the browned beef and onions to a large slow cooker or a stockpot. Add the beans, corn, tomatoes, black olives, green olives, taco seasoning, and ranch dressing mix, and cook in a slow cooker on low for 6 to 8 hours or simmer over low heat for about 1 hour in a pot on the stove. To serve, place a few corn chips in each bowl and ladle soup over them. Top with sour cream and shredded cheese if desired.
