Thayir pachadi (raitha) is the most common yogurt-based vegetable salad prepared in almost every part of India. We prepare thayir pachadi using cooked vegatables or raw vegetables and spice it up with black pepper, chopped green chillies or red chilli powder. Generally, we serve raitha as a side for flatbreads like chapathi, stuffed paratha, etc., and also for spicy rice dishes like biryani, tomato rice, etc.
