This recipe came from All You magazine (April 17, 2009).
8 tsp. olive oil
4 cups baby spinach
4-4 oz. boneless, skinless chicken breast halves
8 oz. white mushrooms, sliced
4 tsp. teriyaki sauce
Preheat oven to 450 degrees. Tear off 4 10-inch squares of aluminum foil. Brush each square with 2 tsp. olive oil. Place 1 cup spinach on each square, slightly off center. Top with a chicken breast half and some mushrooms. Drizzle 1 tsp. teriyaki sauce over each portion; sprinkle with salt.
Fold each piece of foil over to cover chicken and vegetables. Crimp edges together tightly to seal. Place packets on a rimmed baking sheet and bake until chicken is cooked through, 15 to 20 minutes. Serve hot. We had brown rice with this.
