In a large bowl, mix the ground beef, chopped onion, dill, parsley, eggs, ground oats, spices, and salt well until the ingredients are fully combined.

Shape the mixture into medium-sized balls.

Preheat the grill or oven to a medium temperature.

Lightly grease a baking tray with olive oil and arrange the meatballs on it.

Grill the meatballs until they are cooked through and browned on all sides.

Serve the grilled meatballs hot with a green salad or grilled vegetables.
