Cut the apple, pear, orange and mango to bite size pieces. Cut each strawberry into 4, and grapes into half. In a large bowl, add all the fruits.
Now add the black salt, cumin powder, chaat masala and black pepper. Sprinkle the lemon juice. Adding lemon juice prevents fruits from browning.
Gently mix without mashing fruits. Refrigerate for 30 minutes to an hour.
Garnish with mint leaves and serve. Fruit Chaat tastes great when served chilled.
