Time: 30 minutes

  • 1 tablespoon canola oil

  • 1 large sweet onion , sliced

  • 1/8 teaspoon salt plus 1/2 teaspoon , divided

  • 2 tablespoons balsamic vinegar

  • 1/2 cup reduced-fat plain Greek yogurt

  • 2 tablespoons low-fat mayonnaise

  • 2 tablespoons white-wine vinegar

  • 4 teaspoons minced shallot

  • 1/4 teaspoon freshly ground pepper

  • 2 hearts of romaine , halved lengthwise and cored

  • 2 4-ounce cans sardines with bones, packed in olive oil, drained

  • 1 cup halved grape or cherry tomatoes

  1. Place oil, onion and 1/8 teaspoon salt in a small saucepan over medium heat. Cover and cook, stirring occasionally, until the onions are very soft and starting to brown, 12 to 15 minutes. Reduce heat to medium-low if they are browning too much. Stir in balsamic vinegar and simmer, uncovered, until it is reduced to a glaze, 1 to 3 minutes.

  2. Whisk yogurt, mayonnaise, white-wine vinegar, shallot, pepper and the remaining 1/2 teaspoon salt in a small bowl.

  3. Divide romaine halves among 4 dinner plates or place on a large platter. Spoon the dressing over the salads. Break sardines into two or three pieces each and divide among the romaine halves. Top with the caramelized onions and tomatoes.
