• Preheat the oven to 350 degrees.

Fathead Dough

• Place mozzarella cheese and cream cheese in a large microwave safe bowl. Heat the cheeses together in microwave on high for 30-60 seconds. Remove the bowl from the microwave and stir. Continue to repeat the microwave heating until all the cheese is completely melted and combined.
• Next, add the room temperature egg to the melted cheese and stir with a rubber spatula until fully mixed. Add in the almond flour, baking powder and psyllium husk (or oat fiber), then continue to knead the dough mixture until fully combined and resembles a ball of dough.
• Lay out a large baking sheet lined with parchment paper. Place the ball of dough in the middle of the baking sheet. Place another sheet of parchment paper over the dough. Press the dough out into a large rectangle using your hands or a rolling pin. Rectangle should be 14-16” long and 10-12” wide. Remove the top sheet of parchment paper. Set aside.

Spinach Feta Filling

• In a clean microwave safe bowl place the frozen chopped spinach and cook as directed on the package. Remove the spinach from the microwave and place all spinach in a linen or cheesecloth. Squeeze out all the excess liquid from the cooked spinach. You will be left with approximately 1 packed cup of steamed chopped spinach.
• Mixed together the cooked chopped spinach, feta, mozzarella cheese, dried onion, garlic powder, salt, pepper, and egg.

Assemble

• Place the spinach feta filling in the center of the dough running the length of the dough. Leave about 1-2” at top and bottom of the dough. And leave 3-4” of dough on each side of the spinach filling.
• Slice the dough up to the filing mixture in strips. Starting at the side bottom of the dough alternate wrapping the dough over the spinach feta filling. Press and form the dough decoratively over the filing.
• Once the sides are completely covering the top of the dough, fold up the top and bottom of your stromboli to completely encase the ends.

Egg Wash

• Using a fork, whisk an egg for the egg wash. Using a pastry brush, wash the stromboli dough completely with the egg wash. You may not use the complete egg. Sprinkle the stromboli with poppy seeds or sesame seeds if you wish.
• Place stromboli in the oven for 30 mins at 350*. At the end of your baking time you may wish to turn your oven to broil and brown the top of your stromboli for just a minute or 2.
• Let the Spinach Feta Stromboli cool a bit before you slice and serve. Enjoy.
