This is my favourite salad. My mother makes the best version- she uses lettuce, cucumber, onions and fresh dill (which really adds to the flavour) with a bit of salt, lemon juice and extra virgin olive oil. Since I've no access to fresh dill (I know I can get it in the supermarket but I don't as it tends to go off very quickly) I've modified the recipe a bit to try and make it more flavoursome. I use lettuce, rocket, baby spinach, cucumber, drizzle with extra virgin olive oil and add salt and lemon juice to taste. It is really light at refreshing.
