01 - Preheat the oven to 375°F. Line a baking sheet with parchment paper or lightly grease a loaf pan.
02 - In a large mixing bowl, gently combine ground turkey, breadcrumbs, milk, egg, onion, garlic, parsley, thyme, salt, black pepper, and Worcestershire sauce until just blended.
03 - Form the mixture into a loaf shape and place it on the prepared baking sheet or press into the loaf pan.
04 - Whisk ketchup, brown sugar, Dijon mustard, and apple cider vinegar in a small bowl. Spread half of this glaze evenly over the meatloaf.
05 - Bake for 40 minutes in the preheated oven.
06 - Remove from oven, spread remaining glaze on top, then return to bake an additional 10 to 15 minutes or until internal temperature reaches 165°F.
07 - While meatloaf bakes, bring a large pot of salted water to a boil. Add green beans and cook for 3 to 4 minutes until bright green and tender-crisp. Drain and rinse immediately with cold water to stop cooking.
08 - Heat olive oil in a skillet over medium heat. Add garlic if using and sauté for 30 seconds. Add green beans, season with salt and pepper, and sauté for 2 to 3 minutes until heated through. Optionally drizzle with lemon juice before serving.
09 - Allow meatloaf to rest for 5 minutes before slicing. Serve alongside the prepared green beans.
