In large kettle bring water to boil. Add chicken breast. While they are cooking, chop veggies into 1/2 inch chunks. Peels and quarter potatoes. You may leave the leaves from the celery on.
Remove chicken breast and put to side. Add veggies and rice to the chicken water with a can of chicken broth. Add 1/2 tsp salt, 1 tsp pepper.
With knife or I use two forks I shred chicken breast into chunks. Not to small. Put back into water with veggies and rice. Bring to rolling boil, reduce heat and let simmer 2 hours. Season to taste with salt and pepper.
