Use a sharp knife or pizza roller to cut wonton wrappers a few at a time, diagonally in half to form 40 triangles. If using Egg Roll wrappers, cut into four squares, then cut each square in half diagonally to form 8 total.
To Bake:
Arrange triangles in a single layer on baking sheets. Lightly spray with cooking spray, carefully turn, and spray again. Sprinkle with salt if desired. Bake in a 375 degrees oven for 5 minutes or until edges are golden brown. Set aside or store in an airtight container up to 2 days.
To Fry:
Pour vegetable oil to a depth of 1 inch into a Dutch oven, and heat over medium-high heat to 350°. Fry, in batches, 15 to 20 seconds on each side or until golden brown and crisp. Drain on a wire rack over paper towels; sprinkle with salt if desired.
