This is what I'm making tonight:
1 lb ground beef
1 lb box penne pasta
1 jar any kind of spaghetti sauce you like
Brown beef on the saute mode-first wait til it says Hot on your display before you add the beef, and then drain fat.
Put beef back in the pot.
Pour the penne pasta over the beef
Pour the sauce over the penne pasta - do not stir it up
Fill the jar with water and pour that around the sides and push the penne pasta into it as much as you can without mixing.
Put the lid on and cook on manual 5 minutes. It will take a while to come to pressure. Do quick release. When you open the pot it won't look right. Stir it around and let is sit a couple minutes and it will be perfect. I make this a lot. We love it. We put cheese on it after we dish it out because Mr. Stitchnripper can't eat cow dairy and I can.
You can add onions/garlic, etc. with the ground beef. You can add herbs/spices of your choice. Add what you like. Leave out what you don't like.
