Another brilliant recipe from Jim Fobel's Big Flavors . I love those big flavors as much as Fobel does and you can't get a recipe that is much easier than this. This makes a really simple weeknight meal if you have some linguine and grilled beef left over from the weekend. Of course, you can even use roast beef from the deli and that makes it quite simple. Naturally, you can change this up by substituting chicken for the beef and other spices for the cilantro (such as basil). 1/4 cup rice vinegar 2 tablespoons mayonnaise 2 tablespoons extra-virgin olive oil 1/2 teaspoon dried oregano, crumbled 1/2 teaspoon ground cumin 1 teaspoon salt 1/4 teaspoon black pepper 1/4 teaspoon cayenne pepper 8 ounces linguine, broken in half 8 ounces trimmed grilled steak or roast beef, thinly sliced 2 tomatoes, cut into 1/2-inch dice 1 medium sweet onion, peeled, halved lengthwise, thinly sliced, and separated into half-rings 1/3 cup chopped fresh parsley, plus sprigs, for garnish 1/3 cup chopped
