Let's start with the cauliflower. We cut into small florets and, the stems, we cut them also in bite-sized portions. In a pot with water and a pinch of salt, we boil the cauliflower about 5 minutes, until tender but still crisp. Drain and set aside.
In a bowl put the cauliflower, the lettuce leaves well washed and cut, add the chopped cucumber, bell pepper, spring onion and tomato, also diced.
On the other hand, for the dressing, we are going to mix in an airtight container the oil, the lemon juice, a pinch of salt and pepper, to taste, and shake well. Drizzle the salad with this dressing and taste to make sure it is to our liking. Finish decorating with a little parsley and we have a delicious cauliflower salad ready!
