Just like the comfort food of your childhood, these sloppy joes contain all real food ingredients and cook up quickly in your pressure cooker.
Add oil to Instant Pot and press the Saute button. Add onion, carrot, celery, pepper garlic and beef and saute for 4-5 minutes. Press cancel button and drain extra fat. Be sure to use a hot pad as pot will be hot.
Add remaining ingredients, place lid securely on top, and have valve set to "sealing" and press the Manual button. Adjust time to 10 minutes.
After the cook time of 10 minutes, let it sit for 10 more minutes before manually releasing pressure. Remove lid and stir. Sauce will thicken more with time.
