1-2cups shredded cheeseI used about 1 1/2 cups of Gruyere
1tsp.dried or 1 Tbsp. fresh herbs
In a medium bowl, whisk together milk, flour, eggs, and salt until smooth. Alternatively, place everything in a blender and blend until smooth. Set aside for 20-30 minutes while oven is preheating.
Preheat oven to 425 degrees F. Place butter in a 9 by 13" glass baking dish. Heat in oven for 5-10 minutes, until butter is completely melted and foaming. Remove pan from oven and tilt to cover the bottom entirely with the butter. Remove from oven and pour batter into the pan. Quickly top with the diced ham, shredded cheese and herbs.
Bake for about 20-25 minutes, or until it is puffed up and the cheese is golden brown and bubbly. Cool slightly before serving.
