Chicken Vegetable Soup

This is a recipe for Chicken Vegetable Soup that I got from my grandmother. I have no idea if she invented it herself or if it is an adaptation of a recipe that she found on the internet (yes, my grandmother gets on the internet).

Whole chicken or a few chicken legs or a few chicken breasts (This times I used 2- 1lb chicken breasts)
2 cans of chicken broth
3-4 ribs of celery
3-4 large carrots
1 medium onion
2 garlic cloves
1 can dices tomatoes
1/2 cup frozen peas
3/4 cup cooked quinoa
Any other vegetables you have around and want to add

Boil chicken in large pot until cooked. (note: if using chicken breast instead of whole chicken, chicken broth can be used in place of water). Remove from water and chop into small pieces. Reserve water (now broth) and add canned broth.
Add chopped celery, carrots, onions, garlic cloves to boiling water and canned chicken broth. Add salt, pepper and garlic or herbs (to taste) to the boiling water.
Boil until vegetables are cooked. Add frozen peas and cooked quinoa 15 minutes before serving.
Serve hot.
