Cut wonton wrappers diagonally in half to form triangles. Arrange triangles in a single layer on baking sheets - you will need to bake in batches. Lightly spray cut wontons with cooking spray, then carefully flip them over, and spray them again.
Bake in preheated oven for 5 minutes or until edges are golden brown. Set aside to cool.
For dip:
In a medium bowl, stir together cream cheese and sour cream. Add crab, green onion, lemon juice, soy sauce, and garlic; mix well.
Cover and refrigerate for 2 to 24 hours.
If desired, top the dip with sweet and sour sauce and sliced green onions before serving.

Optional: Broil for 1 to 2 minutes for a lightly golden top.
