Arugula and Pepper Frittata

Melt butter in a large ovenproof skillet and sauté peppers until just done.

Combine eggs and milk in a large bowl and whisk until smooth. Stir in arugula and half the cheese; pour over peppers in skillet.

Reduce heat to medium low, and cover. Allow to cook, making sure there is no visible bubbling, until set. Sprinkle remaining cheese on top, cover and cook until cheese has melted.
