In a small bowl, whisk together the honey, lemon juice, olive oil, and salt until well combined to create a light, sweet dressing.
Place the mixed greens in a large salad bowl, fluffing them gently for volume and even dressing distribution.
Drizzle about three-quarters of the dressing over the greens and toss gently until all leaves are lightly coated. Reserve the remaining dressing.
Add the sliced strawberries to the dressed greens, folding them in carefully to avoid crushing the fruit.
Sprinkle the poppy seeds evenly over the salad, ensuring they distribute throughout.
If using optional ingredients (blueberries, mandarin segments, pecans, feta, or chicken), gently fold them in now.
Drizzle the remaining dressing over the completed salad, focusing on any dry areas.
Serve immediately on chilled plates for the freshest taste and crispest texture.
