Step 1

Cut the steak into bite size pieces and place in a container or plastic bag. Add 1 Tbsp of the soy sauce, 1 Tbsp of the garlic, and 1 Tbsp of the ginger. Stir until evenly combined and marinate for an hour.

Step 2

Preheat a hibachi griddle or large skillet to medium high. Add 1 Tbsp of the sesame oil and the mushrooms, zucchini, and onions. Cook 3 to 4 minutes, stirring a few times.

Step 3

Add the remaining 1 Tbsp soy sauce, 1 Tbsp garlic, 1 Tbsp ginger, butter and sesame seeds to the veggies.

Step 4

Move the veggies to one side of the griddle or skillet and add the remaining 1 Tbsp sesame oil and the steak on the other side. Continue cooking the veggies and steak for 3 to 4 more minutes, stirring and flipping throughout.

Step 5

Serve the steak and veggies with yum yum sauce for dipping.
