Step 1

Place frozen loaves on a baking sheet and cover loosely with plastic wrap that has been sprayed with cooking spray or a damp towel. Store in your oven (turned off) until risen 2-3 times their frozen size (2-5 hours depending on the temperature inside your home/oven).

Step 2

Remove one loaf, punch it down and form a ball of dough. Place on a flat floured surface. Roll the dough ball into a rectangle-ish shape. The dough should be thin, about 1/8" thick.

Step 3

Spread sauce over two-thirds of dough up to 1/2 inch from the edges and leaving a 3-inch strip along one long side.

Step 4

Layer the toppings over the sauce. Be careful not to overfill.

Step 5

Gently beat an egg and brush it onto the long strip.

Step 6

Fold the the two shorter sides in and brush them with egg wash too.

Step 7

Starting on the long side opposite of the bare strip, roll the Stromboli in jelly roll fashion as tight as you can. Keep rolling, you want the 3-inch strip to end up on the bottom of the stromboli.

Step 8

Next, move the stromboli to a cookie sheet lined with parchment paper.

Step 9

Cut slits into the top and brush it with the remaining egg wash.

Step 10

Bake in a 450 degree oven for 10 - 15 minutes or 350 degree oven for 20 - 25 minutes.

Step 11

If the stromboli starts to turn too brown, make a foil tent to place over it during the remaining cooking time.

Step 12

Let stand for a few minutes before serving.
