Preheat the oven to 400 degrees. Set up an assembly line with three bowls. Whisk eggs together in one bowl, pour bread crumbs into the next, and mix the oil into the buttermilk then transfer to the third bowl. This will be your dipping sauce. Slice your chicken into approximately ¼” slices and dredge both sides in flour, dip them first in eggs, followed by the buttermilk, finishing with the breadcrumbs. Lay them onto a wire rack placed on top of a baking tray for extra browning or fry them immediately for crispier nuggets (and less time preheating!). Bake at 400F for 8 minutes using any non-stick spray lightly on pan; Flip over chicken nuggets and bake an additional 2-4 minutes or until fully cooked through (when cut open). Serve hot with your favorite sauce.
