Well, I bought a bag of the tofu shiratake (all I've seen in supermarkets here), and I think they're great! Granted, my nose is all stuffed from allergies, but they're not supposed to have their own taste anyway - they absorb the flavor of whatever they're cooked in. When people don't like them I think it's the texture, which worked fine for me. I blanched them in boiling water, and then stir-fried them in with zucchini, mushrooms, and tofu in teriyaki/black bean sauce. The texture is sort of like rice noodles, sort of wet and squishy, but that goes great with asian cooking. I wouldn't imagine them being great in place of spaghetti. But I'm very happy with them. 4 oz of noodles has 20 calories, 2g fiber (I'm pretty sure it's all SF), and 2g protein.
