In a large skillet, heat the oil then stirfry onion, garlic, rosemary, sage, thyme salt and pepper for about 2-3 minutes or the onions are translucent but not turning brown.
While stirfrying, beat the egg in a large bowl. Then add onion stirfry mixture, ketchup, and Worcestershire sauce. Stir.
Add ground turkey and bread crumbs, kneading with your hands until completely combined. Place chicken mixture into a loaf pan.
Preheat oven to 350F. Bake for 1 hour or until a meat thermometer inserted into the center registers 170F.
Remove from oven and allow to stand for 5-6 minutes. Remove from loaf pan and allow to cool. Freeze in freezer container or in ziploc bag.
On Cooking Day
Allow to thaw overnight in fridge. Cut into serving size pieces and reheat in skillet until heated through (can add about 1/2 cup water or chicken stock to skillet to prevent it from getting too dried out, if needed). Serve.
You can brush an additional mixture of ketchup and Worcestershire sauce if desired when cooking before serving.
