In a large pot sauté the onion until translucent with 1 tbsp of olive oil, about 3-5 minutes over medium high heat.
Add in the stock as well as the water and seasonings.
Bring this mixture to a boil and add in the beans from the soup packet. (It may also come with a seasoning packet, you won't need that for this chili!)
Once that comes to a boil reduced to medium heat and let it cook for 30-40 minutes.
Add in the whole chicken breasts and let it boil until they are cooked through. Another 15 minutes.
The soup should start to look quite thick at this point and you may need to add a bit more stock or water.
Once the chicken is cooked, remove it and dice or shred. Then add it back into the pot.
Once the beans are fully tender the chili is done! Enjoy topped with micro greens.
