Preheat the oven to 350°F.

Add 1 tablespoon of Grassland butter to an oven safe skillet. Add vegetables, cook and stir over medium heat 5 to 7 minutes or until tender.

In a large bowl whisk together eggs, milk, remaining butter, salt, and pepper. Pour over vegetables in the skillet. Cook, without stirring, until mixture begins to set on bottom and around edges. Using a spatula, lift the egg mixture so the uncooked yolks flow underneath.

Transfer skillet to oven; bake about 5 minutes or until egg mixture is set. Remove from the oven. Let stand 2 minutes. Slice, and sprinkle feta on top for garnish.
