Preheat your grill. Grill the pork loin according to package instructions.
While the pork is grilling, prepare the slaw. Place the shredded cabbage in a medium bowl. In a separate small bowl, whisk together the yogurt, vinegar, lime juice and hot sauce. Add it to the cabbage and toss. Mix in the pineapple, mango, coconut, green onions and cilantro.
Chop the grilled pork, and serve in warmed tortillas with a couple of spoonfuls of slaw.
Notes
If you are preparing this recipe as GLUTEN-FREE, just be sure to use a brand of corn tortillas that is known to be GF.
You can find unsweetened flaked coconut in bins at Whole Foods Market and similar stores. It's great to buy it this way since you can scoop up what you need and just pay for that.
