Heat olive oil in a medium skillet over medium heat. Add the onion, garlic, oregano, red pepper flakes, salt, and pepper, and sauté until the onions are soft and fragrant, about 5 minutes.
Add the spinach and cook until wilted, 2-3 minutes. Remove from heat and stir in the feta cheese.
Place the turkey breast in a shallow roasting pan. Cut a pocket into the thickest part of the turkey breast and stuff with the spinach-feta mixture. Secure the pocket with toothpicks.
Wrap the turkey breast in bacon, overlapping the slices. Secure with toothpicks.
Cover the roasting pan with foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes, or until the bacon is crispy and the internal temperature of the turkey breast reaches 165 degrees F.
Remove from oven and let rest 10 minutes before slicing and serving.
