Pulse ¼ cup of fresh parsley in a food processor until finely chopped and set it aside. Pulse 1 small quartered onion until finely chopped, then return the parsley.
Add 450g of ground beef (80-85% lean), 2 teaspoons of Lebanese seven spice, ½ teaspoon of ground cumin, ½ teaspoon of cinnamon, ½ teaspoon of ground coriander, and ½ teaspoon of salt. Pulse briefly, just until combined.
Divide into 12 pieces and shape each into an oblong about 1in / 2.5cm thick around a wooden skewer.
Heat a greased grill or grill pan to medium-high. Cook the kebabs for 4-5 minutes per side, until cooked through.
