Place the ground beef and lamb in the bowl of a food processor. Pulse a few times so they're combined.
Add in bread crumbs, onion and garlic. Pulse again for a couple of times.
Add in the egg, dried mint, thyme, paprika, lemon juice, lemon zest, cumin, cinnamon, salt and pepper. Pulse for about 30 seconds until all the ingredients are perfectly combined.
Shape the meatballs using an ice cream or cookie scoop and place them on a baking sheet. If the mixture is too sticky, wet your hands and then shape them.
In a large pan, heat the olive oil and place the meatballs to cook.
Cook the meatballs for about 10 minutes and stir them a couple of times to make sure they're brown on all sides and cook evenly.
Serve with pita, Mediterranean salad and tzatziki sauce.
