Start by marinating the lamb with cumin, paprika, coriander, garlic powder, olive oil and a pinch of salt and pepper. Mix all well together and place in the fridge for at least 30min.
Just before cooking the meat prepare garlic sauce by combining all the ingredients together. Prepare red cabbage and chop feta cheese and set aside in separate serving bowls.
Preheat frying pan on medium heat and place the lamb on to the pan. Cook until browned on each side but still bit pink inside. Place in a serving bowl.
Assemble your tacos by placing cabbage then meat, feta cheese, and garlic sauce. You can add some chopped fresh parsley on top. Have fun with it and enjoy.
