Remove Italian sausage from its casing sauté in pan and chop it up with spatula while cooking
Chop vegetables of choice. Think fairly small pieces as they are going on a pizza.
Take your taco shell and drizzle olive oil, I use the back of a spoon to spread evenly (you don't need alot)
Sprinkle garlic powder evenly across the shell
add vegetables and/or sausage
cover with mozzarella cheese
Add pepperoni
This recipe is a little hard to explain. Simply because it is really up to you what type of ingredients to use. I recommend placing the veggies underneath the cheese layer because they tend to get a little crispy from the oven if they aren't covered.
I have also bought classic pizza sauce (tomato based) and used that if you want a traditional pizza. I am actually not a huge fan of tomato so I adore this super simple garlic version.
