Add the soy milk to a medium pot and heat till just boiling. Remove the pot from the heat, add in the rice, vanilla, cinnamon and sweetener. Give a quick stir, and place the lid on the pot. Leave covered as long as you would when making rice regularly (about 5 minutes).
After the rice has cooked, uncover the pot and place it over medium to low heat. Cook the rice and milk mixture till the milk becomes absorbed by the rice, and the dish thickens a bit (anywhere from 5 - 10 minutes). Viola! Eat it hot or refrigerate for later!
*After you've made the rice pudding, you can add in more cinnamon or sweetener or whatever... raisins are yummy too! Be careful when cooking this: watch your milk or it may burn! Yummy, easy... ricey!
