The only difference is the shape and convenience! The triangle spinach pies are a treat but they require some time. I can say, I can whip up spinach pie pockets any time I want for my family or guests because it is that easy! I use my special ten minute quick dough recipe, shape a large rectangular shape, quickly chop and mix the spinach stuffing, and bake for about 12 minutes! They are absolutely taste the same and are absolutely delicious!
