Ordering take-out Thai food isn't the only way to eat beef satay at home. With precut meat, dry salad-dressing mix, and sesame oil, you get all the flavor without having to wait. The salad-dressing mix eliminates the chopping and mixing required for a complicated marinade; combined with oil, it flavors the beef in minutes. The mix also lends a savory edge to a peanut butter-based dipping sauce. Stick the beef onto some skewers, pop them under the broiler for a couple of minutes, and serve.
In a small bowl, stir together the peanut butter, soy sauce, vinegar, lemon juice, 1 tablespoon of the dressing mix, and 3/4 cup water and set aside.
If the beef strips have not already been flattened, gently pound them flat with a rolling pin. In a bowl, toss together the beef, oil, and remaining salad-dressing mix. Coat each strip of beef well and thread a skewer through it. Broil 2 to 3 minutes per side. Serve the satays hot with the dipping sauce.
