if I may plug what is in my opinion a far superior (and cheaper, and healthier...) Pasta swap: zucchini Pasta

I made this a while back, sprinkled just a bit of salt and pepper on it, saute in a bit of olive oil (I use a bit less than what the recipe said) and I put some feta cheese and diced tomatoes on it. Better than regular pasta actually!! I love the nutty, sweet taste of zucchini and it really has a pasta-like consistency. I bought shiritaki noodles on the recommendation of hungrygirl a while back (I think she is a sponsor/getting paid to plug them so I would take her ravings about it with a grain of salt) and I was unimpressed. We can put a man on the moon but we can't make fake noodles that are halfway decent? There are other veggie imitations that are healthier and tastier IMO.
