This vegan noodles with peanut sauce recipe is one of my favorite easy dishes to whip up on those nights where i'm very hungry, but just don't feel like cooking. This recipe for spicy sesame peanut noodles is both vegetarian and vegan. It can be served hot or cold, so you might make a batch to enjoy again for a take-along lunch the next day. You can make this recipe with any noodles or pasta, including ramen, soba, or spaghetti. This thai and chinese-inspired recipe can be made less spicy by substituting red pepper flakes for the cayenne, or, omit the cayenne altogether. If you're looking for a thai peanut butter sauce that the kids will love, this peanut sauce recipe is even tamer. You can find all of the ingredients in your local supermarket. Cayenne pepper is about half as spicy as the traditional thai bird's eye chili peppers used in their dishes (you can find those at asian markets). But it's peppier than jalapenos, so go easy if you don't like things spicy. You can find cayenne pepper powdered or as dried crushed red pepper flakes.
