Cook linguine according to package directions. Preheat oven to 200°C (400°F). Whisk 15 mL (1 tbsp) hoisin with 5 mL (1 tsp) water; brush over chicken. Sprinkle chicken with salt, pepper and half the peanuts. Bake chicken for 15 minutes or until cooked through; slice into thin strips and set aside.

Meanwhile, halve any large mushroom caps. Heat oil in a skillet set over medium-high heat. Add mushrooms; cook for 1 minute. Add red pepper; cook for 1 minute or until tender-crisp. Add chicken strips, remaining hoisin and chicken broth to the skillet. Bring to a boil. Add the linguine and green onions; toss until hot and well combined. Garnish with coriander and remaining peanuts before serving.
