Preheat oven as instructed in pizza crust recipe (or on package).
Heat olive oil over low-medium heat in a medium sized pan.
Once extremely hot (dip in the tip of one of your vegetable sticks, it has to be sizzling right away), fry about 1/4 to a 1/3 of your vegetables for a couple of minutes until they are crispy, spoon out with a slotted spoon for the oil to drip back into the pan and place on a paper towel lined plate. Repeat procedure until all vegetable sticks are fried and crispy. Do not throw in too many vegetables at a time or they won't crisp but rather be all mushy and sad.
Once all vegetables are fried, cut sausage into rounds and grate Parmesan cheese.
Spread sour cream on pizza crust and salt and pepper to taste, top with Parmesan cheese, place sausage rounds on top and then crispy vegetables at last.
Bake as instructed in crust recipe (or on crust package).
