Step 1: Place the berries and rhubarb in a large bowl and allow to thaw completely.
Step 2: Pour the thawed berries and rhubarb in a pot and stir in the sugar, butter, corn starch and cinnamon; bring to a boil and cook until thickened.
Step 3: Spoon half the mixture in a pie shell and sprinkle the oatmeal over this mixture, add the remaining berry mixture and top with pie shell.
Step 4: Make a few slits in the top pie shell and place the pie on a rimmed baking sheet. (this is to avoid the drippings from making a mess in the oven)
Step 5: Place in a preheated 375 degree Fahrenheit oven and cook for 45 minutes or until crust is cooked and golden.
Step 6: Enjoy!
