This sandwich has become a Complete Package signature dish. He’s made it so often, family and friends consider it a trademark TCP creation. But the truth is the recipe came from The America’s Test Kitchen Cookbook (2001, Boston Common Press). Once he tried it, we were hooked. The recipe may sound less than dazzling at first glance, but it’s packed with tremendous flavor. It’s hard to describe, except to say that everyone who’s ever tried it loves it. Last week, when Mom and two of my sisters were here, TCP broke out the flank steak sandwiches, and they fell in love. They’re that good. The key is a good flank steak and the soy-ginger mayonnaise. If you’re not a ginger fan, don’t worry. Mom isn’t either, but she loved these sandwiches. All I can say is “try them…you’ll like them!”
First, mix up the Soy-Ginger Mayonnaise:
1/2 cup of Hellman’s Mayonnaise (not Miracle Whip, Hellman’s – TCP insists)
1 tablespoon of soy sauce
1/2 teaspoon of honey
1/2 teaspoon of garlic, smashed to a paste
1 teaspoon of fresh ginger, grated on a microplane
1/2 teaspoon of sesame oil
Combine all ingredients in a small bowl and whisk until well blended. Cover and refrigerate until ready to use. You can make this up to one day in advance, and it really tastes best if you make it early so all the flavors come together.
For the sandwiches, you’ll need:
1 1/2 pounds of flank steak, trimmed of fat & patted dry
1/2 teaspoon of garlic salt
Salt & Pepper, to your own taste
1 tablespoon of vegetable oil (if you use a skillet)
1 baguette of French bread (use a good soft one)
The soy-ginger mayonnaise (made in advance)
1/2 of a small purple onion, sliced paper thin
2-3 cups of arugula, washed, stemmed & dried
Season your flank steak with garlic salt, salt & pepper. If you’re using a cast iron skillet, heat it to blazing hot first, add the oil and then add your flank steak. If you’re using an outdoor grill, you can skip the oil and just season it first. Either way, cook your flank steak over high heat until the outside is seared and the inside is medium-rare. Remove from the heat and allow it to rest on a cutting board for 10 minutes. If you have a piece of foil handy, throw it over the steak to keep it warm. While the steak is resting, prep the rest of the sandwich.
Slice your baguette in half lengthwise and toast each half on the grill or in a dry skillet or griddle until lightly toasted. Spread each half liberally with soy-ginger mayonnaise. Cutting across the grain and on a bias (45 degree angle), thinly slice your flank steak and place it on the bottom half of the baguette. Top the steak with purple onion and arugula and put the lid on it. Gently press the sandwich to bring it all together, then slice into 4″ to 6″ segments and serve immediately.
We could talk about side dishes for this meal, but the truth is I never remember what we had with these sandwiches. Pickles? Chips? Maybe. I really couldn’t tell you. They’re so good, everything else becomes a blur. And really, you don’t need anything except a handful of napkins and something cold to wash them down with. Enjoy! And thanks for making these for the girls, honey. You da’ man!
