Peel then grate the yam into a bowl and set it aside.
In a separate bowl, beat eggs & egg whites with herb seasoning.
Add bell pepper, red onion, spinach and a little parmesan (if desired) to the eggs. Mix together.
Spray a hermetic jar (at least 12oz in size) with olive oil then add the grated yam. Pat it down so it covers the bottom part of the jar.
Pour in the egg and veggie mixture, then place it on a baking sheet.
Top it off with a few sprinkles of parmesan (as garnish), then bake in the oven for about 30 minutes at 375F.
