Remove the chicken tenders from their packaging and pat dry with paper towels. Place them into a gallon Ziplock bag, or between two sheets of plastic wrap, and whack the thickest parts using a rolling pin, mason jar or the flat side of a meat tenderizer.
Remove one chicken tender at a time and press into the ground Cheetos, making sure to press the Cheetos onto all sides, then place the chicken on the baking sheet. Repeat until all of the chicken is covered.
