Preheat the oven to 375 degrees. Lightly grease a casserole dish (such as approximately 8”x6” or a 6-cup round) and set aside. Peel the potatoes, cut it into small dice and cook in lightly salted boiling water for 3 minutes or until barely tender. Drain and set aside. Heat the butter and olive oil in a sauté pan over medium heat. When the butter has melted and looks foamy, add the onion and cook for a minute. Add the potato and cook for 5-6 minutes or until the pieces are lightly crispy, stirring occasionally. Add the vegetables and cook for 2 minutes, stirring occasionally, until they have softened. Add the tomatoes, if used, and cook for another minute. Stir in the cream cheese until it has melted into the vegetables. Remove the pan from the heat and let the ingredients cool slightly. Beat the eggs and milk together and pour over the vegetable-cream cheese mixture. Add the shredded cheese and stir gently until the ingredients are evenly distributed. Sprinkle to taste with salt, pepper and parsley. Spoon the ingredients into the prepared casserole dish. Bake for about 45 minutes or until the eggs are set and the top is crispy.
