Salade nicoise : cold rice, tomatoes, cucumbers, olivs (green or black, but black ones give a weird color to the salad), mayonnaise. You can also add thuna, cubes of hard cheese…

Tabbouleh : bulgur, tomatoes, cucumber, oignon, mint, lemon juice, olive oil. You can also add chicken breast, chick peas, raisin, parsley, watermelon…

For these salades, there are tons of recipes. In my opinion, the most important is to have more vegetables than anything else.
