Halve your cherries. If you want the salad to be easy to eat without having to run into any cherry pits, then you should halve 1 cup of red cherries before you put them into the salad. Just cut each cherry in half and remove its pit.
Chop the strawberries, red apple, peach, and kiwi into bite-sized pieces. Place 1 cup (140 g) of strawberries, 1 cup (140 g) of cherries, 1/2 of a red apple, 1/2 of a peach, and 1 kiwi on a cutting board and dice them into bite-sized pieces, measuring over 1 inch (2.5 cm) or so.
