Prep the greens and veggies. Wash and dry the lettuce thoroughly.
Chop into bite-size pieces. Slice the cucumber, tomatoes, pepper, carrot, onion, and radishes. Keep everything cold while you mix the dressing.
Make the dressing. In a small bowl or jar, whisk together lemon juice, Dijon, honey, garlic, salt, and pepper.
Slowly whisk in olive oil until the dressing looks slightly thick and glossy. Taste and adjust—add more lemon for brightness or honey for balance.
Toss just before serving. Add the lettuce to a large bowl. Layer in cucumbers, tomatoes, bell pepper, carrot, onion, and radishes.
Sprinkle with chopped herbs.
Dress lightly at first. Drizzle on about two-thirds of the dressing and toss gently with clean hands or tongs. You want a light, even coat without sogginess. Add more dressing only if needed.
Add crunch and cheese (optional). Top with toasted nuts or seeds and a small amount of feta or Parmesan.
Give it one last gentle toss.
Serve immediately. Finish with a final grind of black pepper and a pinch of flaky salt if you like. Enjoy right away for maximum crunch.
