Melt butter. Using silicone brush or pastry brush, brush baking tray with melted butter.
Separate squares and cut corner to corner to make a triangular shape. Place the triangle shapes back as squares on the baking tray. They can be placed close together and you should be able to get about 24 triangles on one tray. Brush with butter.
Sprinkle with parmesan cheese and parsley if using.
Bake for 5 minutes or until slightly browned.
Repeat until all are baked. Cool and serve (if you can wait that long!).
Notes
Use a baking tray with sides.
Leftover wonton chips can be stored in a zippered bag or an airtight container for up to 10 days.
Baked wonton chips will keep longer than ones that are deep fried.
