A rainbow fruit salad is a fun and colorful way to encourage your child to eat a variety of fruits. Chop up a mix of fruits in different colors, such as strawberries, oranges, pineapple, kiwi, blueberries, and grapes. Toss the fruits together in a bowl and squeeze some fresh lemon juice on top to prevent browning. This vibrant and refreshing salad is not only visually appealing but also packed with vitamins and antioxidants.
