Preheat oven to 450 degrees. Spray a large baking sheet pan and line with parchment paper or foil and spray with cooking spray.
Cut potatoes into small bite size chunks and arrange potatoes and green beans on baking pan. Spray generously with a good quality cooking spray, (I like avocado oil or olive oil spray).
Sprinkle potatoes and beans with 1/2 tsp salt and 1/4 tsp pepper, and garlic powder toss well until everything is evenly coated with seasonings.
Lay pork tenderloin over potatoes and green beans and brush with glaze, sprinkle pork with remaining salt and pepper. Roast for 25-30 minutes, or until thickest part of tenderloins reaches 145 degrees on a meat thermometer. Remove pork from baking pan and set aside to rest.
Toss veggies in broth remaining on pan and broil potatoes and beans for an additional 5-10 minutes, or until cooked to your liking. Enjoy!
