I added shimeji mushrooms in simmered beef!! The beef is marinated the night before, so you just need to cook it though in the morning. It's great when making a bento box in the morning since it's easy.
Marinate the beef with the A seasonings overnight. Shred the shimeji mushrooms in small pieces and wash.
In a pan, heat sesame oil over medium heat. Add shimeji and beef with the marinade and cook though.
Story Behind this Recipe
My son's in high school and always has a big appetite. He loves eating meat, so I added a lot of it here.
Take out the marinated beef from the refrigerator first thing in the morning so that the beef will come to room temperature when cooked. I added grilled tofu for the picture. If you use Japanese beef, it'll be soft and tasty. Add ginger if you like.
