The other difference between caprese salad and this steak topping is that I like to saute the cherry tomatoes just a little bit so that they get a little tender, and that way they also match the nice warm temperature of the steak. The combo of the warm steak and the warm tomatoes are going to cause the cheese to get just light soft and melty in a completely heavenly sort of way. Sprinkle the basil leaves on at the very last minute, since you want them completely fresh.
With this approach, you won’t even need a side dish to go with the steak, since your side dish is actually ON the steak, but I highly advise serving it with some crusty Italian bread to help mop up all the mixed up juices from the tomatoes and the steak and the cheese. Just. Plain. Heaven.
So there you go…a summertime steak supper that you’ll still be remembering fondly when the snow flies.
