This dinner came together around this delicious wasabi mayo that they serve with the tuna sandwich at Lure Fishbar. I work in the same building as Lure, and our magazine has a trade account there, which we always use to order food for meetings with different museum curators. One time, we ordered a couple of the tuna sandwiches, and they gave us a big tub of their housemade wasabi mayo to go with them.
After the lunch was over, and I successfully scavenged the leftovers, I brought home the big thing of mayo with the intentions of searing off a nice tuna steak to go with it for my dinner. Instead, I made this pasta.
