To make the dressing, place the tahini, olive oil, lemon juice, and peeled garlic cloves in a small bowl.
It is best to mix with a blender to a smooth dressing. Alternatively, stir with a spoon or small whisk until smooth.
Add 2 tablespoons of water and the salt and stir again briefly.
In a larger bowl, combine the cooked jumbo beans, halved cherry tomatoes, finely diced onion, and chopped parsley.
Add the tahini dressing and chili flakes and mix well.
