Brown and drain beef and pork in large stew pot. Add remaining ingredients and cook on medium-low heat for 30 minutes. An alternate method is to brown meats and pour meats and all remaining ingredients into a large crock pot or slow cooker and cook on low for 4 to 6 hours.
Garnish soup with chopped green onions, sour cream, shredded cheddar cheese, and Tortilla Chips.
