Peanut noodles (pasta)

There was this little cafe next to our 1st/2nd yr lecture hall that sold overpriced sandwiches. They had this one little boxed lunch with noodles + peanut sauce that I became addicted to. This dish is my attempt to recreate that. 
There's not too much to it. It's whole wheat pasta, strips of zucchini and red bell peppers, 'shrooms + kale. Really whatever vegetable you want. The sauce is a mixture of peanut butter dissolved in soy sauce and Sriracha. I sort of mix + taste until I like it (not too spicy, not too salty, not too clumpy). Thin it out with water if necessary such that it becomes a consistency that can coat the pasta. It's a heavy but deliciously hearty dish.
