Here is the item again:
Piling into the car, Jorge and his friends drove to Little Anthony's Pizzeria (A) and gorged on house specialties, (B) such as, (C) garlic knots, meatballs, and sausage pizza.

You correctly realized that the comma after such as was wrong.

To fix this problem, you removed the comma, like this:

Piling into the car, Jorge and his friends drove to Little Anthony's Pizzeria and gorged on house specialties, such as garlic knots, meatballs, and sausage pizza.

You have correctly employed Punctuation Rule 7:

Main Clause + , + Afterthought Transition + Ø + Details.

Groove one!
