"Excellent main dish. Of course as always I press the garlic, not mince it for a marinade because I want the flavor. Very simple marinade, with a very simple and delicious sauce. Family loved it, even the kids. Tender, juicy and full of flavor. Served it with corn and a Caesar salad."

"This is oh so good. We've grilled it multiple times. If you are out of green onions, don't worry...the sauce is fine without them.

"This is sooo good. You can grill or broil the steak and it tastes equally delicious."

"As a weight watchers member, I rely on the Light & Tasty as well as healthy Cooking and to date all of the 4-5 star recipes have always been a 'hit' with my family. This flank steak recipe in particular - I look forward to enjoying it medium rare at least twice a month."

"have made this recipe over and over - before this recipe flank steak was always tough - a very good recipe addition on my WW plan. The horseradish sauce is the 'icing on the cake' as you would say. A "keeper" says my husband."
