Preheat the oven to 425F. Grease a sheet pan with olive oil or cooking spray.
On half of the sheet pan, make a little tray with aluminum foil. (This prevents the pork juices from making the veggies soggy).
Pat the pork tenderloin dry with paper towels and set into the tinfoil tray.
1 ½-2 pounds pork tenderloin
In a small bowl, whisk together the sauce mixture. Pour the mixture over pork tenderloin and turn the pork tenderloin to coat it.
⅓ cup brown sugar, 2 teaspoons teapsoons garlic, 2 tablespoons soy sauce, 2 tablespoons balsamic vinegar, ⅛ teaspoon crushed red pepper flakes
On the other side of the baking sheet, place the potatoes. Drizzle with olive oil, toss to coat, then season with Italian seasoning, salt, pepper, and parmesan cheese.
1 ½ - 2 pounds Yukon potatoes and/or sweet potatoes, 3 tablespoons olive oil, ½ teaspoon Italian Seasoning Mix, ½ teaspoon garlic powder, ⅓ cup grated parmesan cheese, salt and pepper to taste
Bake in the preheated oven for 45 minutes. Use tongs to turn the pork tenderloin every 10-15 minutes.
Use a meat thermometer to check the internal temperature. Once the pork tenderloin reaches 145F, pull it out of the oven and transfer it to a rimmed cutting board. Tend the tenderloin with foil.
While the pork rests, add the green beans to the baking sheet and return it to the oven.
Cook for 10 minutes until the green beans are tender crispy.

Notes
For a deep golden color, I recommend removing the green beans from the tray, returning the pork tenderloin, and placing the pork on the sheet pan until it is broiled for 1-2 minutes. Be sure to watch it carefully so it doesn't burn!
