In a large bowl, whisk the eggs and milk until frothy. Add the fresh herbs.
Preheat the broiler.
In a medium skillet, heat the olive oil over medium-high heat and add the truffle butter, garlic and onions. Saute until the onions are golden in color. Then add the egg mixture and some salt and pepper. Let sit for a few minutes, and then add the cheeses and place in the oven. Broil the frittata until golden brown on top and cooked through. Garnish with the diced tomatoes placed in a heart shape on top of the frittata. Serve warm.
