1. Preheat oven to 375 degrees. Brush bottom and sides of a nonstick 5-by-9-inch loaf pan with oil. Scatter pasta and tomatoes evenly in bottom of pan. In a bowl, whisk together eggs, half-and-half, and 1/4 cup cheese; season with salt and pepper. Pour egg mixture into pan. Bake 10 minutes. Meanwhile, stir together panko, oil, and remaining 1 tablespoon cheese. Season with salt and pepper.

2. Sprinkle panko mixture over egg mixture. Continue baking until puffed and golden brown on top and set in center, about 30 minutes more (if top is browning too quickly, tent with foil). Let cool 10 minutes. Run a knife around edges of pan; invert egg bake onto a cutting board to remove from pan, then turn top-side up. Slice and serve, with relish and sliced vegetables.
