In a large skillet, heat the olive oil over medium heat. Add the shredded chicken and diced pineapple to the skillet.
Stir in the minced chipotle in adobo sauce, garlic powder, onion powder, cumin, smoked paprika, salt, and pepper. Cook for about 5-7 minutes, stirring occasionally, until the chicken is heated through and the pineapple is slightly caramelized.
While the chicken mixture is cooking, warm the corn tortillas in a separate skillet or directly over a gas flame for a few seconds on each side until pliable.
Assemble the tacos by placing a generous spoonful of the chipotle pineapple chicken mixture on each tortilla.
Top with shredded red cabbage, avocado slices, and fresh cilantro.
Serve with lime wedges on the side for squeezing over the tacos.
