Turn your pressure cooker on to Saute and wait for it to say HOT. When your pot says HOT you can add your meat and start browning it and breaking it up with a spatula.
Season meat with seasoned salt and continue to break it up. It doesn't need to be cooked all the way through because you will still be pressure cooking it.
When meat is still pink, add the diced celery, green pepper, and Worcestershire. Deglaze pot with beef broth and place undiluted condensed soup right on top. DO NOT STIR.
Press Cancel and switch pot to Pressure Cook for 4 min with a 5 min NPR.
While your meat is cooking, cut just the tops off the rolls or your long French loaf if you are using that instead. You will use these for Lids later. Carefully hollow out bottom of roll, leaving a 1/2-in. shell. Note: Do the same with a French loaf. Save the Lid for later.
All of the bread that you removed, should be diced up using a serrated knife or torn into pieces. This will be added back into your beef mixture later.
When meat mixture is fully cooked and pressure has been released. Stir and let cool a bit. Some meat lets out a lot of water. If the mixture is a bit too liquidy, you can turn your pot on saute to thicken. Otherwise it should thicken a bit when cooled.
Add diced bread into the meat mixture.
Fill each roll with about ½ cup of meat mixture. Top each roll with a piece of cheese that has been folded or cut in half. I make folded triangles for mine. Note: If using a French loaf, place enough foil on baking sheet to wrap loaf. Fill loaf with beef mixture and top with 'lid' and tightly in the foil.
Either place sandwich rolls under a broiler to brown and melt the cheese or use your airfryer lid and brown the tops. Carefully transfer your sandwiches to a plate and top with the Lids you cut off earlier.
Serve.
