Preheat oven to 400°F.
For the roasted veggie salad, toss together the peppers, red onion, tomatoes and olives on a large baking sheet. Drizzle with EVOO, salt and pepper. Roast in the oven until lightly brown and tender, about 15 minutes.
While the vegetables are cooking, put a large skillet over medium-high heat with 1/2 inch of EVOO in the bottom of the pan. Set up three dishes on the counter: Fill one with flour, one with the beaten eggs, and the last with breadcrumbs, lemon zest, oregano and seafood seasoning, mixed well.
Season the tilapia filets on both sides with salt and pepper, then dip them in the flour, then in the egg, and finally in the breadcrumb mixture.
