Gather a large mixing bowl. Segment the ripe oranges, chop the pineapple into bite-sized chunks, and halve the grapes. Add the mixed berries and toss gently.

Measure out the chopped walnuts and sprinkle over the fruits. Stir gently to incorporate the nuts without mashing the fruit.

In a separate bowl, whisk together Greek yogurt, honey, lemon juice, and ground cinnamon until smooth.

Pour the dressing over the fruit mixture and gently fold until well coated.

Cover and chill in the refrigerator for at least 30 minutes to enhance flavors.

Garnish with extra cinnamon or berries before serving in a beautiful bowl.
