In a large bowl, combine the sliced cabbage, shredded carrots, and chopped cilantro.
In a small bowl, whisk together lime juice, chopped jalapeño, olive oil, salt, and pepper to make the dressing.
Pour the dressing over the cabbage mixture and toss well to coat everything evenly.
Taste and adjust the seasoning with more salt, pepper, or lime juice if needed.
Serve immediately, or let it sit for about 30 minutes in the fridge to meld the flavors together.
Notes
Use a mandoline for thin, consistent slices of cabbage and carrot.
• Dress the coleslaw just before serving to keep it crunchy.
• Adjust the amount of jalapeño to control the spice level.
• Add a pinch of sugar to balance the acidity and heat if desired.
• Letting the coleslaw sit for a bit after dressing can enhance the flavors.
