Step 1

Brown the beef and turkey with the onions in a large skillet. Drain fat, then transfer cooked meat and onions to a large slow cooker (or stockpot). Add beans, corn, tomatoes, chiles, olives and seasonings; cook in slow cooker on low for 6 to 8 hours (or simmer on low heat for about 1 hour if using a pot on the stove).

Step 2

To serve: sprinkle a few corn chips in the bottom of a bowl and ladle soup over them. Top with desired garnishes.
