Preheat oven to 400° F (use convection roast or air fry mode, if equipped). Heat a skillet over medium-high heat. Add oil to skilled and sauté onions, carrots, and mushrooms for 5-7 minutes until onions turn translucent. Add garlic and cook for one minute. Add spinach or mixed greens and cook for 3-4 minutes until wilted. Remove from heat and place in a bowl to cool for 10 minutes.

In a large mixing bowl, combine ground pork & beef, breadcrumbs, eggs, oregano, ketchup, salt, pepper, granulated garlic & onion, and paprika. Add veggies and mix by hand or spoon until all ingredients are fully combined.

In a roasting pan or cast iron skillet (my favorite), place the meat mixture and shape into a loaf about 2-inches thick. Coat with ketchup.

Place a meat thermometer into the center of the loaf. Roast for 20-30 minutes until the internal temperature reads 145° F. Remove from oven and cover with foil. Let rest for 10 minutes before slicing.

Slice and serve with your favorite sides! Enjoy!
