Start by firing up your grill. Today we’re using the Ninja Woodfire Outdoor Grill so we can smoke and bake on one grill. Add the sliced onions and sausages and smoke at 350 degrees F for 15 minutes or until cooked through.
While the sausages cook, make a tomato sauce by combining the canned tomatoes, basil, olive oil and salt in a blender. We’re using the Ninja Power Mixer Set’s Immersion Blender so we can blend and store leftovers. Blend the sauce until smooth.
Roll the pizza dough out into an 16 to 18 inch square. Leaving a border for rolling, spread out the sauce, sprinkle on the mozzarella cheese. Chop the sausages into thing coins and layer these onto the cheese. Roll the dough up onto its self to make thick log with a seam underneath. Use a paring knife to make 4 to 6 vent holes in the top of the Stromboli. Coat the dough with the beaten egg.
Bake the Stromboli at 400 degrees F for 18 to 20 minutes or until the dough is browned it has an internal temperature of 200 degrees F. We like to finish things up with a little extra grated pecorino cheese, shredded basil and a drizzle of olive oil.
