Couscous chicken soup

1 cup chopped onions about 1/2 of a medium
3/4 cup sliced leeks about 1 medium, white and light green parts only
1/2 cup sliced carrots about 1 medium
1/2 cup chopped celery about 2 ribs
1 tablespoon minced ginger
1 tablespoon minced lemongrass or paste
2 cloves minced garlic
1/2 teaspoon ground turmeric
4 cups chicken stock
8 ounces cooked, shredded chicken (FOR STOVE TOP VERSION) (rotisserie chicken is great)
3/4 pound raw chicken breasts (FOR INSTANT POT VERSION)
1 cup pearl couscous
1/2 of a lemon
salt and pepper
chopped fresh parsley for garnish

Stove Top Directions:
1. Heat one tablespoon of the stock in a 4 to 5 quart Dutch oven or stock pot over medium. When it begins to sizzle, add the onions, leeks, carrots, and celery. Saute until the vegetables are soft, about 6 minutes. Stir in the ginger, lemongrass, and garlic, and heat until aromatic. Sprinkle the turmeric over the vegetables and stir.
2. Add the stock, chicken, and couscous, and bring to a light boil. Reduce heat to maintain a gentle simmer; cook for 15 minutes. Squeeze the half lemon into the soup, taste, and season with salt and pepper to your liking. Top with parsley before serving.

Instant Pot Directions:
1. Turn on the Saute function on your IP. Add the oil and heat until shimmering. Add the onions, leeks, celery, and carrots, and saute until all are soft, about 8 minutes. Stir in the ginger, lemongrass, and garlic, and heat through until fragrant. Sprinkle the turmeric over the vegetables and stir. Turn off the unit.
2. Add the chicken broth, and couscous. Lay the chicken breasts in the pot.
3. Secure the lid and make sure the valve is set to Sealing. Set the Instant Pot to manual high pressure, for 5 minutes. When the cooking is finish, allow to naturally release for 7 minutes, then carefully quick release the remaining pressure.
4. Remove the chicken breasts from the pot and shred with two forks (or chop). Return the chicken to the soup. Squeeze the lemon over the soup (taking care to catch the seeds), and add the parsley. Taste, and season with salt and pepper to your liking.

**With some research may want to see about cutting the chicken ahead of time for the instant pot version.  Not sure if this would overcook it or cause other issues.
