Instapot Beef Stroganoff Sandwiches

This is a recipe I adapted from an Instapot cookbook.  I am not sure you save alot of time with this, and it certainly could be made on a pan on the stove.

1# ground beef
1/4 c. finely diced onion
1# mushrooms, sliced
1 T. Worcestershire sauce
8 Oz. sour cream
1/2 c. beef broth
2 T. flour
2 cloves garlic, minced
2 thick rolls, like kaiser, bollios or french rolls
2 T. butter
2 T. parsley
On saute cook ground beef, onion, garlic, and mushrooms.  Drain off any fat.  Mix in flour.  Add beef broth.  Put top onto instapot and using the manual setting cook for 10 minutes.  Allow to release pressure.  Remove lid and stir in worcestershire sauce, and sour cream.  Cut rolls in 1/2.  Scrap out some of the bread making a bowl inside.  Spread with butter.  Spoon stroganoff filling inside each roll.  Sprinkle with parsley.  Cook at 350 degrees for 10-15 minutes.
