Cooking the fruit over medium heat enhances its sweetness without rendering it too soft. Thin-skinned pickling cucumbers require no peeling. Raspberry jam provides body and sweetness to the vinaigrette. If it's too thick to whisk, microwave at HIGH for five to 10 seconds.
How to Make It
Heat a nonstick skillet over medium heat. Coat pan with cooking spray. Add peach and plum slices to pan; cook 3 minutes on each side or until browned.
Combine jam, vinegar, oil, and salt; stir with a whisk until smooth. Combine 1/4 cup jam mixture, salad greens, and romaine in a large bowl; toss well to coat. Place 2 cups greens mixture on each of 4 plates. Arrange 4 peach slices, 4 plum slices, and about 1/3 cup cucumber on each serving. Drizzle remaining vinaigrette evenly over salads; sprinkle with pepper, if desired. Serve immediately.
