Place the turkey breast skin facing down, out onto a cutting board, or onto the counter over a layer of wax paper if your cutting board is too small. Open the turkey breast up, butterflying it to open it even further: Use a sharp knife to cut through the thickest parts of the turkey on either side of the centre, so that the cut is going outwards parallel to the counter. Don't cut all the way through though, stop about 1/2 or more before the edge. Now you should be able to pull the top section out towards the outside, like the page of a book. Repeat on the other side of the turkey breast.
Cut 5 or so long lengths of kitchen twine and lay them out in about 1 inch intervals in front of you. Roll the stuffed breast over the twine with the seam finishing up on top now. Wrap the twine up to meet at the seam and tie each one tightly to hold the meat firmly. Trim excess twine.
One 2.5 lb side or split turkey breast will feed four comfortably. 2 sides will feed up to six. A full breast will feed 8 or even more, depending on the size.
Choose the size you need, follow all the instructions, using less stuffing and baking the remainder in a dish for about 45 minutes at 350F. A smaller rolled breast will be ready earlier, so use a thermometer to start checking earlier. If you are roasting a small split breast, the initial time at 425F should be reduced to 20 minutes.
I purchase 2-3 wings aside for turkey stock that will work great for this recipe, below is a quick way to do it.
The day before, place the wings, coarsely chopped onions (including the yellow skin), 2 ribs of chopped celery, 1 leek, 3 dried bay leaves, 10 peppercorns, bouquet garni of fresh parsley, sage, rosemary and thyme (sounds like a great title for a song...) into a large stock pot and fill with water. Bring to a boil, then reduce and simmer for 3-4 hours. Strain, cool, refrigerate or freeze. This can be used for the gravy. It also is fabulous to drink as tea, season with a little salt and pepper first.
If preparing the meat earlier in the afternoon, prepare your gravy, and then in a baking dish, pour a small amount of gravy to just cover the bottom of the pan. Add the rested and sliced turkey onto the gravy. Drizzle with a touch more gravy. Cover with foil and reheat at 300F for about 10-15 minutes. Keep the rest of the gravy on the back burner of your stove to reheat.
