In a medium bowl, toss together the sliced apples, granulated sugar, lemon juice, and cinnamon. 

Pour sugared apples into the greased push pan.

Using the same bowl, mix together the brown sugar, flour, rolled oats, and salt.

Pour in the melted butter and mix together with a fork until the ingredients are wet. 

Pour the oat mixture over the sugared apples. 

Create a foil sling by folding a 2-foot piece of aluminum foil into thirds lengthwise. 

Cover the push pan with a paper towel and a piece of foil. (this is to absorb any access moisture. Crimp the foil around the edges of the pan to create a seal.

Close the lid and set the pressure release valve to sealing.

Press the manual or pressure cook button and set it to 8 minutes.

Carefully remove pan using foil sling and remove foil lid and paper towel.
