Mix all the tomato-basil concasse ingredients together and set aside.
Preheat oven to 400 degrees F. Heat olive oil in a large saute pan over high heat. Whisk together the eggs, water, cheese, asparagus, peas, parsley and basil until combined and season with salt and pepper to taste. Pour the egg mixture into the pan and cook until the bottom is golden brown and set. Place in the oven and cook until the frittata is cooked through. Serve at room temperature with the Tomato Concasse.
