Easy Greek Spanakopita Triangles with Spinach and Feta are flaky, buttery pastries filled with warm spinach, tangy feta, and fresh herbs wrapped in crisp phyllo layers. These appetizers disappear quickly at any gathering as they bring that irresistible mix of salty cheese and delicate crunch. This version keeps all the classic Greek flavors in perfectly portioned triangles that are simple to make and even easier to eat.
