Grilled Steak and Peppers Vinaigrette

Preparation Halve leeks lengthwise and cut enough crosswise into 1-inch pieces to measure 8 cups, then wash. Simmer leeks, butter, broth, bay leaf, thyme, 1/2 teaspoon salt, and 1/4 teaspoon pepper in a 12-inch heavy skillet over medium heat, covered, stirring occasionally, until leeks are very tender, about 20 minutes. Uncover and boil until liquid has reduced to about 2 tablespoons. Discard bay leaf and thyme. Meanwhile, heat grill pan over medium-high heat until hot. Brush steaks with 2 tablespoons olive oil and season with 1 teaspoon salt and 1/2 teaspoon pepper. Grill steaks, turning once, about 8 minutes total for medium-rare. Transfer to a plate and let rest 15 minutes. Meanwhile, halve and seed peppers and toss with remaining 2 teaspoon olive oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper. Grill, turning once, until crisp-tender and lightly charred, 6 to 10 minutes total. Cut crosswise into 1-inch pieces. Whisk together vinegar, mustard, 1/4 teaspoon salt, and 1/8 teaspoon pepper in a medium bowl. Add extra-virgin olive oil in a slow stream, whisking until emulsified. Add peppers. Serve steaks over leeks with their juices, drizzle with meat juices from plate, and top with peppers and vinaigrette. Serve with:mashed potatoes
