One of my favorite ways to do turkey is in the pressure cooker. It is perfect for the small confines of our 24' Class C. I start with a 4ish pound breast and it goes into the PC for 50-60 minutes. I use chicken broth for the cooking liquid and season the breast with salt and pepper, sage, garlic powder and poultry seasoning.
I doubt it is possible to produce a more moist, succulent breast using any other method. Pair the bird with my great grandmothers simple {but very tasty} stuffing. Simply saute chopped celery, onion and mushrooms in butter and a little chicken stock and use the same seasonings as noted above for the breast. Chop or tear a loaf of bread {I like whole wheat} and place in a large bowl. Pour the veggie mixture over the bread and mix thoroughly and transfer to a baking dish. Into the oven at 350 it goes shortly after the the breast is in the PC. After 30 minutes top with some seasoned bread crumbs for a nice crunch topping and pop it back in the oven until the breast is ready. Mashed potatoes are an easy fix if you're so inclined. Gravy from mix or canned/bottled will work and my bride takes care of the cranberry relish.
Start to finish including the prep time you are talking about an hour and 20 minutes {+/-} and you can feed 4-6 easily. Having a real oven and a three burner stove top makes this meal easy to prepare and you may draw a crowd as the aroma wafting from the galley is more than a little enticing. Enjoy!
