Cut chicken into 1" chunks. Pat dry with paper towels.
Place chicken chunks in a Ziploc bag with flour and toss to coat.
Put chicken chunks in beaten eggs using tongs and move to the next coating station.
Roll in Panko crumbs to coat and place on a rimmed baking sheet lined with parchment paper or foil.
Bake at 450 degrees F for 13-15 minutes. While this is baking, create the sauce. Begin to stir-fry the broccoli florets in a wok as sauce is finishing.
