To prepare a sweet and sour tvp with pineapple rice recipe, you will first need to prepare the pineapple. Peel, slice, and remove the skin from one pineapple and cut it into quarters. Cut the slices in half lengthwise. Place the sliced pineapple in the microwave-safe bowl and microwave for 30 seconds. Add the water to the saucepan and bring it to boil. Turn off the heat and allow the mixture to simmer for 10 to 15 minutes, until the rice is tender and the liquid has been absorbed.
