How to Make It
Preheat oven to 450°F. Coat a large rimmed baking sheet with cooking spray. Combine turkey, oats, 3 tablespoons ketchup, onion, egg, marjoram, and 1/2 teaspoon salt in a medium bowl. Divide into 4 (4- x 2 1/2-inch) loaves; place, evenly spaced, on pan. Combine Worcestershire sauce and remaining 3 tablespoons ketchup in a small bowl; brush over loaves.
Combine green beans, carrots, olive oil, garlic powder, pepper, and remaining 1/2 teaspoon salt in a large bowl. Scatter vegetables around loaves. Bake at 450°F for 12 minutes. Turn vegetables. Continue to bake until loaves are no longer pink in the center, 12 to 15 more minutes.
