01 - Rinse blueberries under cold water and pat dry with a paper towel. Halve or quarter any larger berries for even distribution throughout the salsa.
02 - In a medium mixing bowl, add the prepared blueberries, finely diced cucumber, chopped red onion, minced jalapeño, and fresh cilantro.
03 - Pour in the fresh lime juice and sprinkle the lime zest over the mixture. Add sea salt and freshly ground black pepper. Gently toss all ingredients together until evenly coated and well combined.
04 - Cover and refrigerate for 10 to 15 minutes to allow the flavors to meld together before serving.
05 - Serve chilled as a dip with tortilla chips, or use as a refreshing topping for grilled fish, chicken, or tacos.
