Preheat oven to 350 degrees. Coat 2 (8-9 ounce) ramekins or Pyrex custard cups with cooking spray.
Add 1 egg white to each dish. Next, crack each whole egg right over the ramekin and carefully add to each dish. Add 1 tablespoon milk on top of each. Sprinkle with a little salt and pepper, if desired. Sprinkle each with 2 teaspoons Parmesan cheese. Place on a baking sheet and bake, uncovered, in oven for about 16 minutes until eggs are set around the edges but still a bit jiggly in the center.
In the meantime, add all the topping ingredients in a small nonstick pan coated with cooking spray. Sauté for 2 minutes until tomatoes are soften.
Remove eggs from oven. Divide the tomato topping among the 2 servings.
