Nowadays, I always get double beans/no rice, which I think has something to do with it. Regardless, though, I don't think the quesadilla-as-wrapper did us any favors. The stiffness of the shell certainly made it difficult to wrap. She did her best, though, and even offered to start over, but it looked good enough, so off I went, extra napkins in tow.
And then I tried to eat this thing. It was BIG. But actually not as unwieldy as I had feared. The cheese had solidified, and so if anything, the shell actually held its shape better than a regular tortilla would have:
Slowly but surely, I gobbled this thing up. Verdict: yummy! But honestly, not that yummy, and certainly not proportionally more yummy than a regular burrito. I asked the burrito maker whether they get many repeat customers for the quesarrito, and the answer was no. I think that will be the case for me as well. But I'm certainly glad I did it!
