Spinach, chunks of paneer cheese and spices make up this vegetarian Indian favorite, typically served with a side of warm naan. Paneer is a unique and versatile dairy product. This non-melting cheese typically has the consistency of tofu (which is actually a recommended substitution if you are preparing the dish without paneer). Second, the making of paneer does not involve rennet. This makes the cheese completely lacto-vegetarian and a key source of protein for vegetarians.
