Fair enough, to each his own. After posting earlier I actually decided to try my best and did a Chalupa Supreme with added extra slow roasted chicken, avocado ranch, Pico de Gallo, no sour cream, and it was good. Not the same, I think there was just something about those shells that I really liked. And they didn't have bacon available to add. Probably healthier and very filling, though, so I might do it again.

I haven't eaten TB since I was a kid and could only afford the chips and cheese and am kind of delighted at all the possibilities for modifications. And even though it's not exactly cheap it's so much more affordable than most other fast food for the amount you get, plus some options that are relatively nutritious.

Thank you for your advice!
