Season the salmon fillet with salt, black pepper, and a pinch of dried dill.
Heat a grill pan or outdoor grill to medium-high heat and cook the salmon for 4-5 minutes per side until it flakes easily with a fork.
Bring a small pot of water to a boil, carefully lower the egg in, and cook for 7 minutes for a jammy yolk.
Immediately transfer the egg to an ice bath for 3 minutes, then peel and slice it in half.
In a large salad bowl, combine the mixed greens, rinsed chickpeas, sliced cucumber, and thinly sliced radishes.
Whisk together the olive oil and lemon juice in a small ramekin with a pinch of salt to create a light vinaigrette.
Toss the salad vegetables with the vinaigrette until evenly coated.
Top the salad with the grilled salmon and the soft-boiled egg halves before serving.
