For the sesame cabbage slaw: Combine everything but the peanuts. Let sit for at least 1 hour, or until the cabbage is slightly softened. Longer is better here, and I'd recommend overnight if you have the time. Serve at room temperature, sprinkled with peanuts.

You could definitely sub in crumbled firm tofu, ground chicken, ground turkey, etc for the beef! You'll need to use some oil when you saute the protein.
