Pre-heat the oven to 400°F.
Place the breadcrumbs in a shallow dish. Pile the parsley, garlic, lemon zest and a little coarse salt on the cutting board. Finely chop the lemon-garlic mixture, then combine with the plain breadcrumbs.
Brush the top of each fillet with EVOO and dip into the breadcrumb herb mixture. Brush a little bit of EVOO in the bottom of a baking pan, then place the fillet in the pan, crust side up. Roast the fillets in the oven until firm to the touch, about 12-15 minutes.
