This recipe puts a healthy spin on the popular Thai dish, Pad Thai. Instead of using rice noodles, spaghetti squash is used as a low-carb alternative. The squash is roasted until tender and then mixed with a flavorful sauce made from peanut butter, soy sauce, and lime juice. The dish is then topped with chicken, shrimp, or tofu and garnished with chopped peanuts and cilantro.
