This is wonderful! My husband was having a fit because I bought flank steak. The next day when we ate it he could not stop talking about how good it was. I did add a little extra garlic. I had two steaks so we had the other the next day. This is a repeat!

This is a basic recipe that I make often! I not only make it with beef, I also use thick chicken breasts and grill them in my stovetop pan. I like to make up about a kilo at a time, then freeze them in individual servings. I take one out whenever I feel the need for some delicious steak or chicken, and just heat it up in the microwave with some veggies on the side. This is a wonderful Somersizing meal. I've got a bunch sitting in the freezer at work, and whenever I have these for lunch I have a bunch of jealous coworkers, the smell is divine!
