At Home: Remove the husks from the corn then cut the kernels off the cob. (this can be done easily by holding the cob vertically, then running the knife from top to bottom along the inside of the kernels as you’re holding the cob. It will take about 4 or 5 runs of the knife to get all the kernels off each cob). Place chicken, corn, black beans, red onion, and jalapeño in a large zip top bag. Place the chopped cilantro and tomato in a small zip top bag. Keep both bags refrigerated until you make the burritos.
