This delicacy was born right here in San Francisco when an old neighborhood pizzeria was purchased by Indians, who started selling Indian food in the place while still offering pizzas. Continued suggestions by the clientele to combine the two resulted in the creation of Indian pizza -- a classic crisp, thin crust layered with spinach as well as sauce, mozzarella, and the toppings of your choice, such as tandoori chicken, lamb, cauliflower, eggplant, and prawns. Sold by the slice and the whole pie, the offerings usually include a vegetarian version spiced with hot pepper, green onions, cilantro, and garlic, a delicious and invigorating combination. One of the cheapest and best snacks ever.
