Preheat oven to 350F.

In a small bowl, combine 2 tbsp ketchup with Worcestershire sauce.

Heat olive oil and sauté minced onion on low heat until translucent, about 3 to 5 minutes.

In a medium bowl, mix ground turkey, sautéed onion, breadcrumbs, egg, 1/4 cup ketchup, salt, and marjoram until combined.

Shape the mixture into a loaf and place in a baking pan. Spoon sauce on top.
