Preheat the oven to 375 degrees F, and lightly grease a 9-inch square baking dish or 10-inch round ovenproof skillet.
Break the eggs into a large bowl, and whisk or beat well. Add the remaining ingredients, with the exception of the optional toppings, and thoroughly combine.
Pour the mixture into the prepared pan and, if necessary, use a fork to evenly distribute the ingredients. Bake for 25-30 minutes or until the eggs have just set in the middle.
Remove from the oven, and serve as is or with optional toppings.
