Pour in the Pineapple chunks, adding salt and pepper to taste and cook for 10 minutes. Then, put the lid on the pan and cook for a further 35 minutes. 6)When the Pineapple chunks become softer, begin to crush them with a fork until shredded. 7)Take the tacos and fill them with layers of salad, pineapple, tomatoes, the chicken and guacamole. Sprinkle with cilantro.
