Preheat the grill to medium-high heat (about 500 degrees).
Mix together the egg, garlic, cumin, allspice, cilantro, salt and pepper in a medium bowl. Add the ground beef and mix with your hands until well combined.
Using a 1/3 cup measure, form 8 disc-shaped meatballs. (They will dome slightly on the grill, forming nicely rounded meatballs.)
ightly dip a wad of paper towels in vegetable oil and, using tongs, carefully rub over the grates several times until glossy and coated. Grill the meatballs, covered, for about 4 minutes per side, or until they are nicely browned on the exterior and no longer pink in the center.
Transfer the meatballs to a serving plate and let rest for 3 minutes..
For yogurt - Combine cucumber, yogurt, salt, pepper powder, lime juice in a small bowl and mix well. Refrigerate until ready to serve.
Serve with the yogurt sauce and couscous, if desired.
You can use full fat yogurt to get better taste
