In a large mixing bowl, whisk together the plain yogurt, honey, and ground cinnamon until the sauce is smooth and well combined.
Set aside 6 of the most beautiful strawberry halves to use for garnish later.
Gently add the remaining strawberries, sliced bananas, blueberries, sliced peaches, and cantaloupe cubes to the bowl with the yogurt sauce.
Fold the fruit into the sauce with a spatula until everything is evenly coated. Be gentle to avoid mashing the softer fruits.
Cover the bowl and chill in the refrigerator for at least 1 hour. For the best flavor and color, you can chill it for up to 24 hours.
Serve chilled, garnishing each portion with a reserved strawberry half.
Add a delightful crunch by sprinkling toasted granola, chopped pecans, or slivered almonds on top just before serving.
