You can use vegetable stock instead of chicken stock.
Better delicatessens and supermarkets sell dried porcini mushrooms, parmigiano reggiano and truffle oil. Or you can buy dried porcini mushrooms here, parmigiano reggiano here and truffle oil here.
Try and buy at least 2 types of fresh mushrooms, 3 is better.
You can substitute parmigiano reggiano with your any good quality parmesan cheese.
If you have never tasted truffle oil, go easy on how much you use, you can always add more.
