Add water, chicken, tortellini, bell pepper, and garlic to your pot. Bring to a boil.
Turn the heat off.
Let sit for about 5 minutes.
Add the butter powder, powdered milk, and sauce mix.
Bring back to a boil for 30 seconds to 1 minute.
Eat! If it’s not thick enough, let it sit around for a bit. It’ll thicken right up.
