Roll the balls first in the flour, then dip them in the other half of the egg, and ad the end in the breadcrumbs.
Repeat this process two times. Add the already crumbed balls, in egg, and then in the breadcrumbs again.
Transfer the balls into wire rack or baking pan and spray or wash them with oil on top.
Preheat the oven on 390F/200C, and bake for 10 minutes, Once they start getting golden brown take them out of the oven spray just a little bit more olive oil and bring them back for another 5 minutes.
Don't over bake them because they will start breaking on the edges.
At the end, I like to squeeze a little bit of lemon on top before consuming and dip them in tartar sauce.
