Preheat the oven to 375 degrees F (190 degrees C). Spray an 11x17-inch sheet pan with cooking spray.
Prepare stuffing: Stir stuffing mix and water together in a bowl. Spread out onto one side of the prepared sheet pan. Sprinkle with cubed butter.
Prepare turkey breast: Mix butter and poultry seasoning together in a bowl; spread under and on top of turkey skin. Place beside the stuffing on the sheet pan.
Prepare green beans: Toss fresh green beans with balsamic vinegar and olive oil; season with salt and pepper. Cover and refrigerate until needed.
Prepare sweet potatoes: Prick potatoes several times with a fork. Wrap each in a damp paper towel, ensuring all excess water has been squeezed out. Microwave each potato separately until they give a little when squeezed, 4 to 7 minutes. Start at 4 minutes and check for tenderness, adding more time if needed. Set aside.
Prepare pumpkin pie: Cut the top off the pie pumpkin and remove seeds and pulp. Combine pumpkin pie mix, evaporated milk, and egg in a bowl and pour into the hulled pumpkin. Wrap the entire pumpkin in aluminum foil, leaving an opening at the top. Place the pumpkin on the sheet pan with the turkey and stuffing.
Place the sheet pan in the preheated oven and bake for 30 minutes.
Remove from the oven and add the pre-seasoned green beans onto a corner of the sheet pan in a single layer. Scatter the chopped pecans and cranberries on top of the stuffing.
Place the sheet pan back into the oven for 15 minutes.
Meanwhile, combine melted butter and brown sugar for potatoes in a small bowl. Remove paper towels from microwaved potatoes; cut a slit down the center of each potato and add the sugar mixture evenly.
Remove the sheet pan from the oven and place the sweet potatoes onto the pan.
Return to the oven and bake for 10 minutes more.
Remove the sheet pan from the oven and add the frozen rolls to the pan. Top the green beans with French-fried onions. Add 3 to 4 marshmallows to each sweet potato.
Return to the oven and continue to bake until the turkey is no longer pink in the center and an instant-read thermometer inserted into the center of each half reaches 165 degrees F (74 degrees C), about 5 minutes more.
Remove from the oven and transfer all dinner items to serving platter. Top turkey with warmed gravy and serve with cranberry sauce.
Return the pie to the oven until it's slightly jiggly in the center, about 25 more minutes.
