Chop onions, garlic, and peppers very fine.
Add oil to a large skillet (*we are using a 12" cast iron skillet to go directly into the oven), and saute your onions and peppers until translucent (about 2-3 minutes).
Add in the garlic for 1 more minute.
Sprinkle the Italian seasoning and garlic powder across and stir to combine.
Add in meatless crumbles and marinara sauce. Stir together.
Cook for 2 minutes, stirring occasionally.
*If using an oven safe skillet, sprinkle 1 cup of the vegan mozzarella cheese, then add your frozen tater tots to the top. *If you are not, transfer mixture to a 9x13 casserole dish and then add the cheese and tater tots to the top. Top with remaining vegan shredded cheese, then add the vegan pepperoni on top.
Bake for 30-35 minutes or until tater tots have cooked through. Broil for a few seconds after if desired for a crispier tots, careful not to burn.
Remove carefully and top with green onions or any favorite pizza toppings like red pepper flakes or grated vegan parmesan.
*Feel free to get creative with your favorite pizza toppings throughout the cooking process.
