For an extra layer of flavor, consider adding a drizzle of your favorite hot sauce or a dollop of guacamole. Feel free to experiment with different toppings! Shredded lettuce, chopped onions, black olives, or a sprinkle of cilantro would all be delicious additions. To make these ahead of time, prepare the beef mixture and store it in the refrigerator. Assemble the bites just before serving to prevent the tortilla chips from becoming soggy.
