I'm not sure what drew me to this sandwich. I think I just had all the ingredients available. You also know by now that I like weird grilled-cheese sandwiches. And this definitely is weird. I'm not sure why it's called "quick-pickled" because you are not pickling it at all, just kind of soaking it in a liquid. It calls for sparkling apple cider but I used apple cider vinegar instead - partially because that's what I had available, and partially because that at least makes it more of a pickle. Except it didn't. What I ended up with was mostly just cauliflower coated in honey-mustard.
Anyway, beyond that, this sandwich was also not as grilled-cheesy as I wanted. I had to take a photo of it in the pan because every time I flipped it or lifted it, it fell apart. The cauliflower coating makes the bread really soggy, really quickly. I have no idea how this could be avoided. And! The cheese doesn't bind it together very well. So I'd flip it but nothing would be stuck together and the bread would break apart.
The redemption here is that the sandwich was pretty good. The apple and mustard and caraway and rye go really well together. It was hard to eat since it kept falling apart, so I wouldn't make it again. But I do feel like you need to know that at least it was delicious.
