This was a really tasty and lovely sandwich. I'll post the recipe for the tzatziki tomorrow.
Greek Meatballs (from Closet Cooking)
1 tsp olive oil
1/2 onion, finely chopped
4 cloves garlic, minced
450g lean ground lamb
large handful breadcrumbs
zest 1 lemon
1 tsp oregano
1 tbsp dill or mint, finely chopped
salt and pepper
Heat the oil in a pan, add the onions and fry until translucent. Add the garlic and remove from heat.
Put the remaining ingredients in a bowl, add the onion and garlic and mix well to combine. Divide the mixture into small pieces and roll into balls.
Heat a small amount of oil in a frying pan and brown the meatballs for about 8-10 mins.
Serve in a pitta bread or wrap with tomato, red onion and tzatziki.
