This popular Southeast Asian street fare is known as mee goreng (fried noodles). Look for the sweet bean sauce and noodles (which are sometimes frozen) at Asian markets; substitute dried linguine for lo mein. You can always use less chile paste to make a milder version.
To a slow cooker chicken, I added an old family noodle recipe. If you want it to be more like a soup, add another quart of broth. This was a fixture at family reunions when I was a child, and the slow cooker makes it even easier.
