Try a novelty ........ a guy in my locality has come up with creating spicy Keema Pizza and Chicken Tikka Pizza..... best of both worlds. It tastes good and his business is booming.
A new idea is definitely the works.
if you are lucky enough to find a novelty or fad that stands the test of time a lot of money can be made. most novelty or fads dont stand the test of time unfortunatly and you have to try to make the novelty in such a way so that it cant be easily copied
