If you’d like to use fresh mushrooms instead of dried, add about 4-8 ounces of sliced mushrooms when you add the zucchini. You can also substitute other vegetables for the zucchini and add a half cup of frozen peas along with the tofu. On nights when I’m running short on time, I’ve been known to skip the chopping and add a 1-pound bag of frozen vegetables to my tofu (Italian blend with broccoli, zucchini, and peppers is our favorite).
