One of the fanciest restaurants we’ve ever been to is the Kronenhalle in Zurich, and we’ve been lucky enough to go there several times for business dinners. My favorite thing to get there is their avocado appetizer, which is simply an avocado halved, with red wine and shallot vinaigrette on top. It’s ridiculously easy to make, and at $15, it’s ridiculously expensive. I know, I sound like a chump for ordering it. When we came back from this recent trip, we recreated it at home, for less than $1 a serving. Delicious.
