Brush pork with olive oil. Sprinkle evenly with garlic salt and paprika.
Grill pork over medium heat 10 - 12 minutes or until desired doneness, turning halfway through cooking and brushing with 1/4 cup of the Hot Sauce. Let rest 5 minutes.
Meanwhile, brush pineapple with remaining 2 tablespoons of Hot Sauce. Grill pineapple over medium-high heat 3 minutes per side or until tender and lightly charred. Grill poblano halves 3 - 4 minutes or until lightly charred, turning once. Remove pineapple and peppers from grill. Cool slightly; chop into bite-size pieces.
Slice pork and serve in warmed tortillas. Top with pineapple, poblano peppers and cilantro. Drizzle with additional Hot Sauce, if desired.
