This salad -- boasting tangy apples, funky Gorgonzola, and crunchy hazelnuts -- is satisfying enough to pack for a light lunch.
Preheat oven to 350 degrees. Place hazelnuts on a rimmed baking sheet, and toast until golden, 5 to 8 minutes. Let cool; coarsely chop, and set aside.
In a large bowl, whisk together oil and vinegar; season with salt and pepper. Add endive, apple, Gorgonzola, and hazelnuts; toss gently to combine. Serve immediately, garnished with more Gorgonzola, if desired.
