Prepare the Zucchini: Grate the zucchini using a box grater and place it in a mixing bowl. Salt the grated zucchini generously and let it sit for 20 minutes to draw out moisture.
Squeeze Out Moisture: After 20 minutes, transfer the zucchini to a colander lined with paper towels. Squeeze out as much liquid as possible to ensure a firm crust.
Mix Ingredients: In a separate mixing bowl, combine the drained zucchini, eggs, flour, Cabot cheeses, and Garlic Junkie seasoning. Mix until well combined.
Preheat the Traeger: Preheat your Traeger grill to 400°F while you prepare the crust.
Prepare the Cookie Sheet: Line a cookie sheet with parchment paper and spray it with non-stick spray to prevent sticking.
Shape the Crust: Dump the zucchini mixture onto the parchment paper and shape it into a circle about 12-14 inches in diameter and 1/2 inch thick.
Cook the Crust: Place the cookie sheet on the Traeger grill and cook for about 30 minutes, rotating once, until the crust is brown, bubbly, and firm.
Add Toppings: Remove the crust from the Traeger and let it cool slightly. Top with tomato sauce, pepperoni, sausage, and a generous amount of Cabot mozzarella cheese.
Final Cook: Return the pizza to the Traeger for an additional 10 minutes, or until the cheese is golden and bubbly.
Serve: Allow the pizza to cool slightly before transferring it to a cutting board. Slice with a pizza cutter and enjoy!
