Preparation Heat olive oil in a large saucepan over medium heat and cook onions for 4 to 5 minutes or until translucent. Add garlic and cook an additional minute. Add the whole chicken breasts, stock and salt to the saucepan, cover, bring to a boil and reduce to a simmer. Cook for 18-20 minutes, remove chicken to a plate and allow to cool. While the chicken is cooling, add the remaining ingredients to the pot. Remove the chicken from the bone, chop into bite-size pieces, and add to the pot.
