Here in Rhode Island, when snow is on the way, everyone runs to the store for milk and bread. My pantry always holds a full complement of Asian condiments, plus several types of rice to steam up in my little rice cooker, so I run to the store for fresh ingredients to mix and match in enough stir-fry dishes to see us through any storm. This recipe takes one of my basic stir-fry sauces and gives it a twist with the addition of peanut butter. The amount of Sriracha makes this moderately spicy, so adjust for your own heat tolerance. These days, you can find Sriracha in most grocery stores, but if you don't have it on hand, a few red pepper flakes will stand in nicely.
