Preheat your Grill to medium (approximately 375°) and oil or butter an 8-inch cast iron pan. Scatter all the bagel pieces in the pan evenly.

In a large bowl, whisk together eggs, heavy cream, everything bagel seasoning, cream cheese, & salt. To make things easier I use a blender and blend until the mixture is nice and frothy.

Sprinkle sausage and cheese over bagels. Then pour egg mixture over bagels and sausage making sure to coat all the bagel pieces.

Cover with foil and bake for 20-30 minutes. Remove foil and bake until the top of the quiche is golden and eggs are cooked through.

Let it rest and set up for 10-15 minutes.
