For the meat sauce:Â Heat the oven to 375Â°F. Mist a 2 1/2 quart baking dish with cooking spray. Warm the oil in a large skillet over medium-high heat. Add the onion and salt and cook until golden and tender, about 5 minutes, stirring often. Add the ground beef and cook until no longer pink, crumbling the meat with the spoon, about 5 minutes. Add the garlic, cinnamon, oregano, and dill and cook 1 minute while stirring.
