Heat oil in an oven safe medium skillet. Add onions and tomatoes. Saute until onions are soft.
Add arugula and sauté until wilted.
Add salt and pepper to eggs and whisk well. Pour eggs over vegetable mixture.
Dot top with goat cheese. I find it easy to use two spoons. Scoop goat cheese on one spoon and push it off with the other.
Bake for 10 to 15 minutes in a 350 degree preheated oven until the center sets Don’t over cook.
Taste for seasoning and adjust.
Serve warm or at room temperature.
