Cheesy Chicken and Broccoli Pasta

Thanks to tasty.co for this recipe. I've change the recipe a bit because there are way too much pasta than the chicken and broccoli. Four member of my family can eat this as part of our weekly menu.

Ingredients for 4 servings

2 tablespoons olive oil
2 chicken breasts, cut into 1 inch (2cm) pieces
salt, to taste
pepper, to taste
½ cup yellow onion, about half an onion, diced
2 cloves garlic, about 1 tablespoon, minced
1 can 14.5 oz chicken broth
1/2 cup water
8 oz pasta shells
4 cups broccoli, or one head of broccoli
1/4 teaspoon cayenne powder
1/2 teaspoon nutmeg
1 cup milk
2 cups shredded cheddar cheese

Preparation

1. Heat olive oil on medium heat in a large pot. Add chicken breasts, season with salt and pepper, and allow the chicken to brown on one side. 
2. Flip chicken, then add onions and garlic as the second side browns. 
3. Once the chicken has browned on both sides, add chicken broth, water, and pasta to the pot. 
4. Stir all ingredients, cover the pot with a lid, and bring to a boil. When it begins to boil, uncover and stir. Bring the heat to low, stir, then cover and let simmer for 20 minutes or until the pasta is al dente. 
5. After 20 minutes has passed, uncover and add in the broccoli. Stir continually as the broccoli steams until the rest of the liquid evaporates. 
6. Add milk and cheddar cheese and stir until the cheese melts and you have a smooth cheese sauce. 
7. Add salt and pepper (to taste), cayenne, and nutmeg. Stir once more, then you’re ready to serve. 
8.  Enjoy!
