Preheat broiler.
Heat the oil in 10-inch nonstick, ovenproof skillet. Add sausage and saute until it begins to brown, about 3 minutes. Add mushrooms and saute until golden, about 3 more minutes. Stir in garlic and sage and cook another 30 seconds.
In a blender combine the eggs with the heavy cream, pepper, Essence and salt and process briefly until frothy. Pour the egg mixture into skillet and cook, undisturbed, until the sides and bottom are set but center is loose, about 4 minutes.
Place under broiler and cook until mixture is just set on top and cooked through, about 3 to 4 minutes. Cool 2 minutes, invert onto plate and serve.

1 tablespoon black pepper
1 tablespoon onion powder

1 tablespoon dried leaf oregano
