Tabbouleh can be made in many different versions, for example, by adding diced cucumber, lettuce or other vegetables, according to personal taste. So, give it a try.
Collect any tomato juice from stage 2 and add to the couscous.
When you taste at the end of the recipe to check the seasoning, you can also adjust the acidity of the Tabouleh (add a little lemon juice) or its smoothness (add a little olive oil) to your taste.
