Ready those toppings! Fresh, frozen or canned, get that corn off the cob and set aside to sprinkle on later. Remove black beans from can and rinse in strainer. Dice up the red onion. For 8 hot dogs, about half a large red onion should do it. Grab some ready-made guacamole from the grocery store or make your own by mashing some fresh avocados. Mix in diced jalapeños and a pinch of cilantro for even more flavor!
