Although these are not traditional empanadas because they are made with puff pastry dough, they are still very popular, especially for breakfast. They are often shaped as a square, maybe to distinguish them from the classic round empanadas. The light and flaky pastry combines perfectly with the melted cheese and ham. If you've been resorting to commercially-prepared hot pockets for quick breakfasts, lunches, and snacks, this can be your go-to alternative. You can make these empanadas and freeze them unbaked, then take them straight from the freezer to the oven for a quick hot treat. Your kids will love them as they are simple but delicious. Pair them with a big green salad bursting with vegetables for lunch or servings of fresh fruit for breakfast. You can also pack these in brown bag lunches as they taste great at room temperature as well as hot.
