There is the Mexican pizza big box combo meal. I was a little disappointed it didn't come in an actual box. Why call it a big box combo if there is no box? That's most blatant case of false advertising since the Neverending Story. Oh, there is a drink there too, but it's out of frame.
I'm sure you've guessed the "pizza" is the thing in the bottom left hand corner. It's a layer ground beef and beans sandwhiched between two burrito(?) shells with cheese, pizza sauce and stuff on top. It was surprisingly edible. The combo also comes with a hard taco, the cinnamon twists and fries. Taco Bell fries are nasty, so I got tacos and then upgraded them to tacos supreme. They were supremely delicious.
Even though Taco Bell is less than a 10 minute drive from where we live I rarely eat there. Maybe only two times a year. I'm almost ashamed to say I went back a week later to get another Mexican pizza. I don't know why and I can't help myself.
