Cut the courgettes into long thin strips using a peeler, and discard the soft, seeded core. Toss the courgette ribbons, peas and radishes together in a large bowl. Whisk the oil, lemon zest and juice, and yogurt together, then toss with the veg.

Put the pea shoots, dressed veg and large flakes of salmon on a large platter. Finish with a good grinding of black pepper, and scatter over the mixed seeds and dill to serve.
