Pre-heat the oven to 400°F.
Lightly dress fish with EVOO; season with salt and pepper and arrange in a glass baking dish.
Combine the breadcrumbs, garlic, oregano, parsley, red pepper, chili, olives and onions in a bowl and dress with just enough EVOO to lightly coat.
Arrange the topping all over the top of the fish and around the dish.
Scatter the feta around and over the bread layer.
Bake the fish for 20-25 minutes.
Serve with lemon wedges on side.
