Slice the sweet potato thinly, then julienne. Soak in a bowl of water for a little while.
Into a heatproof container, microwave for 3 minutes at 500 W. Once it's soft, it's done.
While you're microwaving the potato, mix the ☆ ingredients together.
Let the sweet potato cool slightly, mix with the ingredients from Step 3. You don't have to wait until it's completely cool.
Plate, scatter sesame seeds, and it's done!
It's even better with lettuce.
Story Behind this Recipe
I had this once at a teppanyaki restaurant and it was delicious, so I recreated it!
Microwave the sweet potato until it's cooked through but not totally mushy. If serving to adults, season with plenty of wasabi. It's seasoned lightly so children can eat it without problems. It's also good with mustard instead of wasabi.
