Heat two tablespoons of oil in a wok or a pan, add garlic and stir fry for half a minute. Add spring onions, capsicums, French beans, carrots and cabbage and continue to stir fry for a couple of minutes more, stirring and tossing continuously.
Add white pepper powder, salt, MSG and soy sauce and cook for half a minute. Set aside to cool. Divide prepared filling into twenty four equal portions. Place a portion of the filling in the center of each wonton wrapper, wet the edges with a little water, fold into half diagonally, twist the ends and stick.
Repeat this process to prepare all the wontons. Heat sufficient oil in a wok, add prepared wontons and deep fry for two to three minutes or until crisp and golden brown. Drain on absorbent paper. Serve hot with Sichuan sauce.
