Butternut Chicken and Banana Soup

2 tablespoons coconut oil
6 skinless, boneless chicken breast halves, cut into chunks
2 cups chopped celery
1/2 cup chopped red onion
2 tablespoons curry powder
4 cloves garlic, minced
4 cups chicken broth
2 cups water
1 (15 ounce) can light coconut milk
2 cups butternut squash cubes
2 (10 ounce) cans diced tomatoes with green chile peppers
3/4 cup sweetened shredded coconut
2 firm bananas, thickly sliced

1. Melt coconut oil in a large pot over medium-high heat. Saute chicken in hot oil until browned completely, about 5 minutes; add celery, onion, curry powder, and garlic and continue to saute until the onion is tender, 8 to 10 minutes more.
2. Pour chicken broth, water, and coconut milk into the pot; add butternut squash, diced tomatoes with green chile peppers, and coconut. Bring the liquid to a boil, reduce heat to medium-low, and cook the soup at a simmer until the squash is soft, about 40 minutes.
3. Stir sliced bananas into the soup; simmer until soft, about 5 minutes more.
