Prep Spinach: Melt butter in a non-stick skillet, add frozen spinach, and thaw. Add more fat or water if needed.

Add Spices: Add minced garlic, salt, and pepper to the skillet once the spinach water has evaporated. Mix well.
3 garlic cloves, ¼ teaspoon salt, ¼ teaspoon pepper
Add Cheese: Add diced feta to the spinach mixture, cook until cheese melts and forms a paste with spinach.
7 oz feta cheese
Season: Taste the filling, adjust salt, pepper, or acid if needed, especially if using cream cheese.
Cool: Let the filling cool for 20 minutes to evaporate extra water before using.
