Ever since I found out I could get my hands on Wagyu Beef in Vancouver, I can’t stop serving this when company comes over. It’s a really simple, quick hors d’oeuvre.

The ingredients are easy enough to swap out and play around with on Crostini. If you can’t get Wagyu, swap the recipe out for filet mignon. If you’re not a fan of horseradish, Dijon mustard would be delicious!

I love the wagyu because all you need is a super quick trip to cast iron over high heat and it is still incredibly tender. No marinating or effort required.
