-If the fresh ginger and garlic are too complicated, you may substitute bottled ginger and garlic in the produce section. Rosemary (fresh herb section) is available in the produce section too. If you don’t want to buy fresh, use dried Rosemary. That will work. It won’t be AS good, but it will work.
-If you are a Costco person, they sell very good Flank Steaks in a two pack. You can freeze the second one for Fathers Day ;)
