In A Medium Bowl, Mix Together The Chicken Pieces And Garlic. Toss With The Flour Just To Coat, And Shake Off Excess. Heat The Margarine In A Large Skillet Over Medium-High Heat. Add The Chicken Pieces; Cook And Stir Until Browned. Add The Mint Leaves And Lemon Juice, Cover And Steam For About 5 Minutes, Just Until The Chicken Is Cooked Through. Do Not Over Cook The Chicken Or It Will Be Tough.
