In a large mixing bowl, mix together all the lamb kofta ingredients except the olive oil and then season with salt and pepper
Shape the mixture into small, bite-sized koftas (about the size of a walnut). Set them aside in the fridge to chill until ready to cook
Meanwhile, combine all the tzatziki ingredients, season with salt and pepper and chill in the refrigerator until ready to serve
To cook the koftas, heat the olive oil in a frying pan over medium-high heat
Cook the koftas in batches, turning occasionally, until they are browned on all sides and cooked through (about 8–10 minutes)
Remove the cooked kofta from the pan and rest on a plate lined with paper towels
To serve, top each cracker with some tzatziki, a couple of the lamb koftas, fresh dill and a sprinkle of the chopped pine nuts
