Using a small sharp knife cut into the thick end of the chicken and make an incision reaching 2/3 the way down the breast.
Loosen up the incision with your fingers to make a hole.
Season the chicken with pepper.
Combine the cheese with arugula and baby spinach and stuff the breasts. Spiral-wrap the breasts with the bacon tightly to cover the meat evenly. Place chicken on a nonstick baking sheet and roast 20 to 22 minutes until bacon is crispy and chicken is firm.
Place the potatoes in a pot and cover with water.
Bring to a boil, season water with salt and cook potatoes 15 minutes, or until tender.
Bring 1-inch water to a boil.

Place the potatoes back in the hot pot after draining.
Coat the potatoes with 2 tablespoons oil, the scallions, chicken stock and salt and pepper.
Toss for 1 minute.
Serve chicken with green beans and potatoes alongside.
