Place a dry frying pan over medium heat and add the cashew nuts. Toast them, stirring constantly, until they are golden and fragrant, about 3–4 minutes. Remove from heat and let cool.
While the nuts cool, chop the cucumber, bell pepper, and red onion into small, uniform pieces for even bites and vibrant color.
In a small bowl or jar, whisk together freshly squeezed lemon juice, honey, salt, pepper, and olive oil until the dressing is shiny and well emulsified.
Once the cashews are cooled, roughly chop them if larger pieces remain, then add them to a large mixing bowl along with the chopped vegetables.
Pour the dressing over the vegetable and nut mixture, then gently toss everything together until evenly coated and the salad looks vibrant and glossy.
Let the salad sit for about 5 minutes to allow flavors to meld and the vegetables to slightly soften, then give it a final gentle toss.
Serve the Cashew Crunch Salad in a wide bowl, garnished with extra herbs if desired, and enjoy its crisp, bright, and satisfying textures.
