Lettuce Salad with Candied Walnuts, Oranges and Feta

• 1 cup walnut pieces
• 2 Tbsp water
• 2 Tbsp sugar
• 1/4 cup white wine vinegar
• 1 tsp grated orange peel
• 1/4 tsp dry mustard powder
• 6 Tbsp olive oil
• 1 large head lettuce, leaves torn
• 2/3 cup coarsely crumbled feta cheese or blue cheese (about 3 oz)
• 2 oranges

1. Preheat oven to 325°F. Scatter nuts on rimmed baking sheet. Add 2 Tbsp water and sugar; toss until sugar dissolves and syrup coats nuts. Roast until water evaporates and nuts are crisp, stirring once, about 15 minutes. Cool on sheet.

2. Whisk vinegar, orange peel, and mustard in small bowl to blend. Gradually whisk in olive oil. Season dressing with salt and pepper.

3. Combine lettuce and cheese in large bowl. Cut peel and pith off oranges. Cut between membranes, releasing orange segments. Add segments and walnuts to salad. Toss with enough dressing to coat. Serve, passing remaining dressing.
