Core the cabbage and slice very thinly. I used a mandoline, but a sharp knife works perfectly well. Place in a large bowl with the grated carrot, scallions, jalapeno and cilantro. Toss to combine.
Add the lime juice, olive oil and salt to the cabbage mixture and combine well. Taste for seasoning.
Notes
*Leave the seeds if you like it hotter. Sometimes I swap some of the oil for a little mayonnaise or chipotle mayonnaise.
