How to Make It
Preheat oven to 350°F. Spread nuts on a lined baking sheet and toast until fragrant, 7 minutes, shaking once. Let cool.
Whisk lemon juice, mustard, honey and oil in a medium bowl. Season with salt and pepper.
Place spinach, endives and pear in a large serving bowl and drizzle with dressing. Toss to coat. Sprinkle salad with nuts and cheese, or serve with nuts and cheese on the side. Serve immediately.
