Place the frozen dragon fruit, strawberries, and peaches in a large bowl. Microwave on the defrost setting for about 4 to 5 minutes. The fruit should remain cold but begin releasing its juices.
Pour the partially thawed fruit and all the flavorful juices into a large pitcher or punch bowl. These juices form the fruity base of the sangria and enhance the vibrant color.
Slowly pour both bottles of rosé wine or Chardonnay into the pitcher. The wine blends beautifully with the fruit juices and creates the signature sangria flavor.
Add the vodka and stir gently. This ingredient adds depth to the drink while allowing the fresh fruit flavors to remain the focus.
Add the lemon-lime soda and stir once more. The carbonation gives the punch a refreshing sparkle and balances the richness of the wine.
Fill serving glasses with crushed or cubed ice. Pour the sangria over the ice and add extra fruit pieces for garnish before serving immediately.
