Rocca leaves are great at soaking the dressing, the longer the prepared salad is left to sit, the juicer the leaves are.
Use a salad spinner to gently dry rocca leaves after washing, they are delicate and will bruise easily if roughly handled. This goes for any salads with rocket.
Preparing ahead can be achieved by keeping the chopped vegetables together separately to the prepared rocket salad dressing (in a jar) both in the fridge. Then storing the dry roasted walnuts in an airtight container in the pantry. Combine all ingredients when ready.
Variations
This rocca salad can be built upon, depending on other foods or availability I have used this base salad to add any of the following (dressing amount may need adjusting);
Button mushrooms - I normally quarter the smaller button mushrooms
Pomegranate - add an amazing sweetness and crunch to salads with rocket
Pear or apple - freshly cut slices
Beetroot - cooked and peeled or canned works well
Tomatoes - any type is good, even sun-dried tomato
Artichoke - either roasted, steamed or marinated works well.
Dressing for rocket salad can be adjusted to include pomegranate molasses or balsamic vinegar/glaze.
Walnuts can be omitted.
