Turn your crock pot on high and place all the ingredients (except bouillon, cornstarch, parsley, and lemon juice) into the crock pot with the chicken on the top veggies on the bottom grains in the middle.
In a separate bowl add the bouillon and about ⅔ cup of water and microwave for a minute.
Take the bouillon and water out and break up the bouillon the best you can until it is lump free.
Mix the cornstarch into the bouillon water with a fork or whisk, until it is lump free, then add it to the crockpot.
Cook on high in your crock pot for 5-8 hours
After 5-8 hours use a spoon to remove the chicken, shred it with a fork.
Place shredded chicken back into the crockpot and stir to blend all the ingredients.
Pour the lemon juice into the crockpot, and taste to make sure that it has enough lemon, salt and pepper for your liking.
Spoon into bowls, and garnish with fresh parsley and a lemon wedge.
