Bake for 15-20 minutes, tossing potatoes halfway through.
Remove potatoes from oven. Add sliced sausage to the sheet pan with the potatoes, toss to coat in seasoning, and return pan to the oven to continue cooking. Bake for approximately 15 more minutes; but during the final 5 minutes of cooking time add the green beans to the sheet pan, toss to coat in seasonings, and return to the oven to finish. The meal is ready when the green beans are tender and the potatoes are crispy on the outside and tender on the inside.
