Preheat the oven to 350°F (175°C).
Cook the diced potatoes until tender, about 10-12 minutes.
In a large bowl, whisk together the eggs, milk, and heavy cream until well combined.
Add the cooked potatoes, sausage, shredded cheese, spinach, and herbs to the egg mixture.
Transfer the mixture into a greased baking dish and bake for 30-35 minutes, or until the center is set.
While the main dish bakes, prepare a simple fruit salad with the fresh berries.
Once the main dish is baked, dust with powdered sugar and serve hot.
