1 cup sliced stemmed shiitake mushrooms
8 large omega-3 eggs
1 cup diced Fontina cheese, divided
1/2 teaspoon salt
1/2 teaspoon ground black pepper

Melt butter in heavy broilerproof 10-inch-diameter) nonstick skillet over medium heat.
Add leeks and sauté 4 minutes.
Add asparagus and shiitake mushrooms, sprinkle lightly with salt, and sauté until tender, about 6 minutes.

Add egg mixture to skillet; fold gently to combine. Cook until almost set.
Sprinkle remaining 1/4 cup Fontina cheese and Parmesan cheese over.
