Preheat your oven to 325°F (163°C) and prepare a greased baking dish or loaf pan.

In a large mixing bowl, combine the egg, oats, salt, and pepper. Mix thoroughly before adding the ground turkey.

On a sheet of foil, pat the turkey mixture into a rectangle measuring 12x9 inches.

Melt butter in a skillet over medium heat and sauté the onion and celery until tender, about 5-7 minutes. Stir in water, sage, thyme, and stuffing cubes.

Spread the stuffing mixture evenly over the turkey rectangle, leaving a 1-inch border.

Roll the turkey mixture from the short side, carefully peeling the foil away as you go.

Place the rolled turkey seam-side down in the loaf pan and lay bacon strips over the top.

Bake uncovered for 60-70 minutes, until the internal temperature reaches 165°F (74°C) and bacon is crispy.
