For the fruit salad, wash the carambola and cut them into slices. Wash the strawberries, remove the green and cut them into slices. Wash and slice the kiwi and mango as well. Peel the banana, slice it and drizzle with a little lemon or lime juice to prevent it from turning brown.
Mix all the fruits in a bowl and drizzle the fruit salad with Grand Marnier.
Divide the fruit salad among 4 bowls and serve with whipped cream or ice cream.
