Adding a few slices of banana, pieces of fruits like peaches, or chopped fresh strawberries can give the pie an extra dimension and make it even more delicious.
Try adding a few tablespoons of your favorite jam, honey, or syrup to your store-bought strawberry pie filling mixture before adding it to your dessert.
Cinnamon or cinnamon sugar could be a tasty addition to your strawberry filling. You could also try a pinch of nutmeg, cardamom, or ginger can all work well in this recipe to give it a unique flavor.
Vanilla or almond extract can both be used to give the pie filling an extra layer of flavor. Just add a few drops directly to the filling before you put it into your dessert of into the oven for a subtle, but delicious result.
