Chicken soup

Hi. We got here in Portugal a soup that we call here "canja", and there is no exact translation for english. It's just a portuguese word. It's just a chicken soup. You boil the chicken really well in much water, and you also put in a peeled oignon that is boiled at the same time that the chicken; and then you remove the boiled chicken. With a dowel. Then in the water that was used to boil the chicken, that you don't throw away, you put in a container (maybe plastic), you boil rice. The chicken has to be boiled in like a lot of water, so when the chicken is already boiled, the water that remains, that was the water used to boil the chicken, is enough to make a soup. In that water you boil maybe 1/2kg of rice. You put some salt. And after maybe 10 minutes, the time it takes so that the rice is properly boiled, the soup is ready. It's a really nice soup. Very old recipe. It also can be done instead of chicken, with duck or turkey. In the plates where you put the soup, you can put little pieces of the boiled chicken. Thanks
