Mix crab meat, cheese, onions and mayo.
Gently place one wonton wrapper in each muffin cup cup, allowing edges to extend above sides of cups. Fill evenly with crab meat mixture. Bake 18-20 minutes or until edges are golden brown and filling is heated through.
Serve warm. Garnish with chopped green onions, if desired.
NOTE: Low-fat cream cheese and mayonnaise can be used.
