In a saucepan, place cubed sweet potatoes and cover with water; bring to a boil, reduce heat, and simmer until sweet potatoes are almost tender.

Drain sweet potatoes and set aside for now.

In a stockpot, heat the olive oil and brown the pieces of chicken on all sides.

Add the chicken broth and half-cooked sweet potato cubes and bring to a boil; reduce heat, add the remaining ingredients, and simmer until the chicken is thoroughly cooked and the sweet potatoes are tender.
