Notes

For an even creamier dish, use 2 cans of chicken soup
For extra spice use Rotel instead of diced tomatoes
To cook pasta in Instant Pot, break in half, use 4 cups water, 2 tablespoons butter, 1 teaspoon salt, and pressure cook for 4 minutes. Allow 1 minutes natural release, then quick release, stir well, and don't drain.
