Combine citrus: In a small bowl, whisk together the fresh orange juice, honey, and lime juice until the honey is completely dissolved, about 1-2 minutes of stirring.
Taste and adjust: Taste the dressing and add more honey if you prefer it sweeter, or more lime juice if you want extra tang.
Prep berries: Hull and slice the strawberries thickly, leaving blueberries and blackberries whole as they are the perfect size.
Segment citrus: Peel the mandarin oranges and carefully separate the segments; if using canned, drain well and pat dry with paper towels.
Dice pineapple: Remove the skin and core from fresh pineapple, then cut into bite-sized chunks, discarding any tough core pieces.
Cut kiwi: Peel each kiwi with a vegetable peeler or sharp knife, then dice into uniform bite-sized pieces.
Halve grapes: Cut the green grapes in half if you prefer, or leave them whole for a quicker prep.
Combine fruit: Transfer all the prepared fruit to a large bowl, mixing gently with a large spoon to combine without bruising the delicate berries.
Pour dressing: Pour the honey-citrus dressing over the fruit and toss gently until everything is evenly coated, about 1-2 minutes.
Chill and serve: Cover the bowl and refrigerate for at least 30 minutes before serving to allow the flavors to meld, though you can serve immediately if needed.
Garnish: Just before serving, top with fresh mint leaves, coconut flakes, or chia seeds if desired for extra flavor and crunch.
