I made this for my husband's bento box (in the picture you'll see I also made a side of corn) and it was delicious!! I cut the steak very small. I added chopped sweet onions to the potatoes and steak, and they were a perfect addition. Also, the potatoes took forever to cook? So I put them in microwave for 6 minutes to soften. That is why they look mushy. I should have microwaved first, then grilled them. (*>.<) It was still delicious!
(Corn recipe: boil corn on cob, cut off cob, cook with butter, salt, pepper, and onion powder. Ta‐da!)
