If desired you can start cooking the veggies before they go in the crockpot. Place diced veggies in a skillet. Sauté with a little olive oil over medium heat, until soft. If the skillet gets dry, add a little water to the skillet so they don’t burn. Keep adding a little water until they are soft. This allows you to keep this meal in E mode without adding too much fat.
Dump everything into your crockpot. Cook on low for 5-6 hours. When it is done, remove your chicken breasts and cut into small pieces.
Optional, use a blender or immersion blender to blend up some of your veggies or even all of them.
Serve hot.
