Preheat the oven to 375 degrees. Fill one mixing bowl with the flour, another with the whisked eggs, and a third with the panko, paprika, salt, and pepper. Stir to evenly combine the panko mixture
Dredge each cauliflower piece in the flour, until evenly coated, then dip in the egg mixture, and finally in the panko mixture, pressing the panko gently against the cauliflower to thoroughly coat
Place cauliflower pieces on a medium-size sheet pan and freeze them. After frozen divide into groups of 4 pieces wrapped in plastic wrap. Put back in the freezer
