Cut the chicken breast into cubes and mix it in a large bowl with the orange juice, lemon, soy sauce, olive oil.
Season with salt and pepper and leave to soak for 2, 3 hours.
Then put the fried chicken breast in a Teflon pan without adding oil and after 5 minutes add the diced pineapple. Put the lid on and let it simmer well. At the end we add the hot pepper flakes.
