Tilapia Tacos with Watermelon Salsa

Description
This is best assembled the same day it will be served, but the red chili salt, watermelon salsa, chipotle crema and slaw can be prepared hours ahead.

This recipe makes more of the salt and salsa than you'll need for this dish. Use the leftover salt mixture on french fries, pork roast or grilled chicken breasts.
