DRESSING
To make the dressing, mix together the yogurt, mayo, tahini, mustard, Worcestershire sauce, anchovy paste, garlic powder, lemon juice, grated parmesan, black pepper, and salt in a small bowl until smooth and creamy.
CROUTONS
Preheat oven to 375°F.
Mix together olive oil, minced garlic, salt, and black pepper in a small bowl.
Transfer the cubed bread to a baking tray. Toss in the olive oil mixture and make sure each piece is coated evenly.
Bake for 10 to 15 minutes or until the bread is dry and crispy.
Toss in the fresh parsley and grated parmesan and allow to cool to room temperature before adding in to your salads.
SALAD
In a large salad bowl, add the chopped lettuce, cucumbers, black olives, sumac, dried cranberries, and parmesan.
Add as much or as little dressing as you like. Toss the salad in the dressing.
Right before serving, mix in the croutons so they don't get mushy. Enjoy.
