Cook the hard boiled eggs using your preferred method (boil them or cook them in the Instant Pot). When they are cooked, place them in an ice bowl to stop the cooking. 

Carefully peel the eggs and slice them in half. Remove the egg yolks and place them in a food processor. Set the egg whites aside.

Prepare the filling by adding baby spinach, mayonnaise, salt and pepper to the egg yolks. Process until smooth. 

Spoon the spinach mixture into a piping bag and pipe the filling into the egg whites. 

To finish, make tiny little circles (I think of them as holly berries!) from a slice of roasted red pepper (the jarred kind is perfect). You can cut tiny pieces by hand or use a straw to make more even circles. I think about three per deviled egg looks good.

Store in the fridge until required.
