Couscous with Spiced Zucchini and Tofu

I was given a large, green, round summer squash a week ago, and I decided to make this recipe with it. It kind of looked zucchini-like so I thought I could just substitute it. This was just okay. The squash didn't taste at all like zucchini - it was more, I don't know, squashy - and the skin was a lot tougher. I threw in some pan-fried tofu to make it more of a substantial meal - I used a different brand than I usually do, and it was just okay. I can tell when a meal bombs when my husband goes to the fridge and gets out the barbecue sauce. Oh well. At least it wasn't turnip soup bad. It was okay, it just wasn't that flavorful.
