Preheat the oven to 425F. Line a large sheet pan with foil.
In a medium bowl toss green beans with olive oil and seasonings. Spread out on half of the sheet pan.
In a medium pan, add olive oil and heat on medium high. Sauté veggies for 3-5 minutes, or until softened.
Set aside to let cool.
In a medium bowl combine ground beef, ground turkey, oatmeal, salt, pepper, garlic powder, onion powder, dried ground mustard, Worcestershire sauce, milk, egg, and sautéd veggies. Mix well to combine, but do not over mix as meat can become tough.
Divide mixture into 6-8 equal portions. Shape each portion into a small free form individual “meatloaf” and add to other half of the sheet pan.
Bake 30 minutes in the center of the oven, turning the green beans halfway, until meat is cooked through (160F in center) and the beans are slightly charred.
While meatloaf is cooking, combine 2 tbsp ketchup and 1 tsp Worcestershire sauce. When meatloaf is cooked, top with ketchup mixture (see notes).
