Great question — answering as the UphillTech team:
The three-stage flour/liquid/breadcrumbs coating is standard, and each of the stages is there for a reason. You can skip the pre-dust if you like (the initial dredge in flour) but the coating won’t adhere as well. If those steps are too complicated, you should be able to find frozen pre-coated chicken pieces at big-box grocery stores and restaurant cash-and-carry places. Those can simply be cooked in the air fryer.
