• Transfer the zucchini mixture to prepared quiche pan. Pour egg mixture over top of the zucchini mixture, spreading the egg and cheese mixture around to completely coat roasted veggies.

💭 Tips

• Whisk the eggs well with a hand whisk or blender. This will add air to the eggs, making them fluffier and well incorporated.

• Add a splash of heavy cream to the egg mixture for fluffier eggs.
