Cheesy Gordita Crunch is the correct answer, but probably best to also try basic items just for comparison.
I remember the dark days when the Cheesy Gordita Crunch was a limited time offer and it kept going away and coming back. I would always go A LOT when it showed back up. So glad it seems to be a stable staple now.
Oh! And fwiw - they actually sell the Fiesta sauce in some grocery stores now... that is one of the key ingredients that makes it so good. That sauce goes well on/in so many things.
