Wash the lentils and make sure they are free of any debris.
Add them to a medium sized pot and boil in three cups of water with half a teaspoon of salt. Bring the water to a boil and cook them on medium heat for about half an hour or until soft.
In the meantime, chop your veggies: dice the tomatoes, cucumbers, and bell pepper. Loosely chop the parsley, scallions, and green chili (with gloves!) if using.
To make the dressing, add the lemon juice, olive oil, salt, zaatar, smashed garlic, tahini and water to a jar. Close the jar and shake it to combine all the ingredients homogeneously.
Assemble the salad: veggies, herbs, and cooled lentils. Add the dressing, mix, and enjoy!
