Slice bananas diagonally, 1/4-inch thick; set aside.
Put ice water in a medium bowl. Stir in tempura batter mix, pumpkin pie spice, and cayenne pepper. Do not over stir. (Batter will be thin and lumpy.)
Heat 2 inches of oil in medium saucepan to 350 degrees F. Working in batches, dip sliced bananas in batter then slide into hot oil. Fry for 2 to 3 minutes or until golden brown. Remove from oil and dust with powdered sugar.
For the Coconut-Green Tea Sauce
In a small saucepan, over medium heat, bring cream to barely a simmer. Reduce heat to low and add tea bags. Steep for 8 minutes. Remove bags and stir in coconut sorbet until melted.
Serve hot Fried Bananas in a small pool of Coconut-Green Tea Sauce. Garnish with fresh berries and mint.
