01 - Gently rinse and thoroughly dry the blueberries. Halve them if desired for a more tender texture and easier eating.
02 - In a mixing bowl, combine the blueberries, diced cucumber, red onion, jalapeño, and fresh cilantro.
03 - Add the lime zest, lime juice, sea salt, and freshly ground black pepper. Stir gently to coat all ingredients evenly without crushing the blueberries.
04 - If using, carefully fold in the diced avocado and/or red bell pepper, taking care not to mash the avocado.
05 - Taste the salsa and adjust salt, pepper, or lime juice as needed to balance the flavors.
06 - Refrigerate for 10 minutes before serving to allow flavors to meld. Serve with tortilla chips, alongside grilled fish or chicken, or as a taco topping.
