Prepare vegetables into uniform stick shapes: cucumber into long strips, daikon and carrot into 5cm sticks, and bell pepper into short strips.
Sprinkle salt over the vegetables and let sit for about 10 minutes. Drain any excess moisture.
Place the vegetables in a clean airtight container or food-safe bag. Add Kewpie Lemon Dressing until they are submerged. Refrigerate and marinate before serving.
Tips
For best flavor, let the vegetables marinate for a few hours or overnight.
Use clean tools and containers to ensure safe storage and freshness.
