In a medium-sized skillet, heat the grapeseed oil to medium. Add the mushrooms and saute, stirring frequently until golden brown and soft, about 3 to 5 minutes. Add the chopped steamed broccoli, sun-dried tomatoes, and garlic. Saute, stirring occasionally until garlic is fragrant, about 3 minutes.
Pour the beaten eggs evenly over the veggies and allow them to cook, untouched, about 1 to 2 minutes. Use a spatula or wooden spoon to stir the mixture together until eggs are fully cooked, about 2 to 3 minutes. Sprinkle with desired amount of sea salt and serve.
*If using raw broccoli, saute the broccoli with the mushrooms until softened. If necessary, add a couple tablespoons of water while sauteing the veggies to help them steam.
