cook spinach in a little bit of water till fully cooked, take off the heat and allow to cool
When spinach is cool squeeze out all of the water from the spinach (excess water will make the stuffing loose)
in a mixing bowl add in the softened cream cheese, mayonnaise, egg and old bay seasoning. Whip together until well blended.
fold in the spinach, roasted peppers, shredded mozzarella and crab meat (make sure crab meat has been well-drained, squeezing out any excess water). Mix gently and if the mixture is too loose you may add a little bread crumb to tighten it up.
