Tzatziki sauce: Squeeze the water out of the grated cucumber and put the cucumber in a bowl. Add the yogurt, 1 clove of minced garlic, and 1 tsp of lemon juice and stir to combine. Season to taste with salt and pepper and drizzle with olive oil. Set aside.
For the patties: Combine the lamb, 4 cloves of minced garlic, spices, ginger, onion, 1 Tbsp lemon juice, and chopped olives, chickpeas, and cilantro. Divide and shape into 6 patties.
Brush the patties lightly with olive oil and grill on high direct heat for about 7 minutes total.
To assemble the burgers, divide the Naan bread into 12 equal pieces. Spread the hummus evenly on the 6 bottom pieces. Place the lamb patties on the hummus and top with the crumbed feta and Tzatziki sauce. Finish off with bread.
