Walking tacos are a popular way of serving Frito pie at parties. Prepare the beef and bean mixture as described in the recipe. Then transfer to a crockpot or Instant Pot to keep warm during the party. Provide mini Fritos or single serve Frito bags and complete your walking taco station with all your favorite taco toppings, such as sour cream, salsa, guacamole, pico de gallo, sliced black olives, sliced jalapeños, cilantro... Guests tear open the Frito bags, scoop some warm chili mixture on top of the crunchy Fritos and add as many of their favorite toppings as they like. Yum yum!
