Apple, Grape & Walnut Salad with Blue Cheese

Sweet meets tangy and peppery in this cold-weather-inspired meal. It’s terrific on any occasion—even special enough for a holiday dinner. The best part is you can make it in under 20 minutes. The only cooking required is toasting the walnuts; we suggest not skipping this step, as it really adds a lot of flavor to the final dish. The simple dressing is a tried-and-true combination of olive oil, red-wine vinegar, and Dijon mustard. Simply toss with the arugula, romaine, grapes, and apple, top with the walnuts and cheese, and it's ready to serve. This salad is also wonderful with diced or shredded Cheddar cheese instead of blue cheese.
