At the bottom of our Original Petro® is a Fritos® Corn Chips or Pasta base. Next, we ladle our signature layer of your choice between our signature chicken or plant-based chili. Finally, customize your Petro® with cheddar and jack cheese, diced tomatoes, fresh green onions, sour cream, and to top it off the optional black olives and jalapeños! Be sure to also ask about our amazing Premium Petro's with additional exciting toppings!
