Cut cabbage in half & slice thinly, place in medium size salad bowl. Chop onion and add to cabbage.
Rinse cilantro if needed. A salad spinner is very handy to use to dry lettuce as well as fresh herbs. Add cilantro to cabbage. Sprinkle with juice of one small lime. Salt & pepper to taste
If you like a bit of spice, add a deseeded and diced jalapeƱo. A bit of advice, wear disposable gloves while handling any hot pepper to prevent any skin or mucosa burns.
