Directions

1. To make marinade, combine pineapple juice, honey, Sriracha sauce, Worcestershire sauce and crushed garlic. 
2. Place pork cubes in a plastic zipper bag. Cover with marinade and place in the refrigerator for 3 hours. 
3. To make the yogurt dip, mix all the yogurt ingredients in a bowl, cover, and refrigerate. 
4. In a small pot, boil sweet potato cubes with 2 tablespoon salt until al dente (about 5 minutes). Rinse under cool running water. 
5. Once your pork has marinated, sweet potatoes are cooled and pineapple cubed, skewer each ingredient one by one. I prefer 6" metal or wooden skewers. 
6. To cook, use a charcoal grill, gas grill, griddle, or cast-iron pan. Heat all to smoking hot. 
7. Lightly brush vegetable oil on all sides of your loaded skewers and season with salt and pepper. 
8. Once your grill is hot, prepare your grill grates or cooking surface by adding oil to a paper towel and hold with tongs to rub grates or cooking surface. 
9. Add skewers to the grill over the hottest areas. Turn and cook on all sides, brushing with reserved marinade. 
10. Once skewers are grilled on all sides, remove from the grill and serve with pineapple chili yogurt dip.
