When I walk home home for lunch I always pass this lady selling fruit from a cart. She takes the same route each day and we often meet at the same place. Today I chose papaya (มะละกอ ma-la-gor) which cost only 20 Baht. It is very cheap and convenient as she has already peeled the fruit for you. But, on a hot day, make sure that you buy in the morning as the fruit might spoil if out in the sun all day.
