1Put the peas in a large heatproof bowl. Cover with boiling water. Let stand for 5 minutes until thawed. Drain.
2Put the peas, green onions and stock in the blender and secure lid. Blend on the SOUP program until the program finishes and the soup is smooth.
3Add the mint leaves and cream and secure the lid. PUREE for 30 seconds until combined.
4Pour the soup into a saucepan. Stir over medium heat until hot. Season with salt and pepper. Divide among serving bowls. Top with a dollop of yogurt or sour cream and garnish with extra mint leaves.
Tip: If using fresh stock and serving the soup chilled, bring the stock to the boil and boil for 2 minutes, then allow to cool until there is no visible steam before blending.
