Thai Beef Salad. What a lovely way to enjoy a good piece of beef. I know most recipes call for using lean flank steak. And while I’m sure that’s very nice on this salad, on the rare occasion that we have steak, I prefer the most tender cut I can find. And that would be a filet. Grilled to medium-rare. Sliced nice and thin. It was that thought alone that inspired this recipe post. Every bite of this Thai Beef Salad is a flavor explosion.
