Preheat the oven to 350 degrees. Coat a small ramekin with cooking spray.
Place a couple of tomatoes and some Parmesan into the ramekin. Crack an egg into the ramekin, being careful not to break the yolk. Add the milk, a few more tomatoes and Parmesan to the top. Season with sea salt and freshly cracked pepper, to taste.
Place onto a baking tray and cook for 5 minutes; Turn the oven to broil and cook for another 5 minutes or until the whites are set but the yolk remains soft. Meanwhile, place a piece of bread into the toaster and toast. Butter the toast then cut into 4 equal strips. Remove the egg from the oven and serve with the soldiers immediately. Enjoy.
