What if you made a cheeseburger into a healthier soup packed with veggies and calcium? That's what we have here, and it's delicious!
Set the pressure cooker to saute. Cook ground beef and chopped onions.
While the meat is browning, chop potatoes, green beans and carrots (if not using pre-shredded carrots.
Add water, bouillon, salt and chopped vegetables to beef and onion mixture. Cancel saute setting, put lid on pot and set to pressure cook for 8 minutes.
When time is up, perform quick release. Remove lid, return to saute setting and add 2 cups of milk, and cheeses. Stir cornstarch into other 1/2 cup of cold milk. Add mixture to pot. Stir frequently until cheese melts and soup thickens.
