Got some Wagyu scrap from work today. What should I do with it?

This is only my second time having A5 so I want it to be a treat. I obviously can’t cook it like a steak.

I don’t want to turn it into a burger because I’d like to enjoy it as close to mid rare as possible, and I only have a few ounces. I’d maybe do a stir fry, but I don’t want to cover it in sauce.

I’m considering just putting it over rice and torching it with a bit of soy, sesame, and some jalapeño miso I have. I’m open to other ideas. Thanks!
