Easiest thing ever.
Either use a mandoline (left portion) or use a knife to cut strips
Then mix 4 parts mayo, 2 parts light soy sauce, small part of dark soy sauce, 1 part of rice vinegar, sesame oil and toasted sesame seeds to taste.
Adjust for acidity and if you use low sodium soy sauce like I do add some salt to the cabbage a tad before adding the sauce.
Works well with carrots added to the cabbage.
This one is indeed related to our objective of having at least 2 meals full vegetarian a week. It's actually super succesful especially with the kids.
