Spinach triangles are a smaller, hand-held version of the traditional Greek spanakopita, which is typically made in a large baking dish. These smaller-sized gems are filled with a savory mix of spinach, cheese, and dill, wrapped in layers of flaky phyllo dough. Perfect as appetizers or snacks, spinach triangles offer the same delicious flavors as the full-sized dish in a more convenient, single-serving format.
