Directions:

Preheat oven to 350 degrees F. Chop the sweet onion, broccoli and cherry tomatoes.

Heat the olive oil in a cast iron skillet or other oven proof skillet over medium heat. Add the onion and broccoli and coat with the olive oil. Add the water and saute the vegetables until the water has evaporated and the broccoli is tender, about 10-12 minutes. While the vegetables are cooking, mix the eggs, milk, salt, pepper, and garlic powder.

When the vegetables are done cooking, add the tomatoes to the skillet and evenly mix and distribute the vegetables over the bottom of the skillet. Pour in the egg mixture and let it sit over the heat for 2-3 minutes until a crust is formed on the sides and bottom of the skillet. Top with the grated parmesan.

Bake for about 35 minutes, or until the frittata puffs up in the middle, is firm, and golden brown on top.
