This instant pot taco soup is an excellent all-in-one dish to make for a family meal, potluck, or game day get-together. Aside from the great flavors, one of the best things about this soup is the time it takes to prepare and cook it. You will have full-flavored, hearty taco soup in just one hour. This version contains ground beef and two kinds of beanspintos and black beans. Feel free to use whatever you happen to have in your pantry. Navy beans, garbanzo beans, great northern beans, and kidney beans are all good alternatives. Serve taco soup with corn chips or fried tortilla strips (see below) and shredded cheese, along with optional garnishes of sour cream, chopped cilantro, avocado wedges, or guacamole.
