Everyone loves a barbecue, especially when it’s as delicious as this easy, inexpensive main dish. When marinated, flank steak is as tender as more expensive cuts and extra tangy with sorrel sauce spooned over.

This makes a quick and easy weeknight dinner for the family because the marinade can be prepared the night before or in the morning. Place the flank steak in the marinade and refrigerate until ready to barbecue.

Serve with tiny new potatoes grilled on the barbecue, fresh asparagus or spinach-stuffed tomatoes, and a fresh green salad.

About Sorrel


Sorrel is a perennial herb, easy to grow in North American herb gardens, and very popular in French cooking. It has a wonderful, slightly sour taste of wild strawberries. Sorrel can be washed and torn into bite-sized pieces and added to salads or pureed into a hot or cold soup.

If sorrel is unavailable, substitute spinach, but add ½ teaspoon of fresh lemon juice to add the sour flavor. Arugula, which has a peppery taste, can also be used as a substitute.
