Preheat oven to 350F degrees. Spray a 9-inch pie pan or square pan with nonstick spray. Set aside. Combine spinach, artichoke hearts, garlic, tomatoes and crab in a bowl. Stir thoroughly. Add salt, pepper, dill and Italian seasoning, stir till well blended. In a large bowl, whisk the eggs, egg whites, milk, salt, and pepper together until thoroughly combined. Arrange veggie/crab mixture in the prepared pan. Tap down with a fork to create a complete layer. Top with shredded cheese (save Romano for very top), then pour the egg mixture on top. Sprinkle with grated Romano cheese. Bake for one hour, uncovered at 350 degrees. Cool for 10 minutes on a wire rack before slicing and serving.
