Heat the oven to 190C/fan 170C/gas 5. Blanch the broccoli for 2 minutes in boiling salted water, drain, and roughly chop. Pat dry with kitchen paper.
Beat the eggs, milk, quark, and season. Fold in the salmon, broccoli, and chives. Spray a 20cm shallow tart tin with oil, and pour in the mix. Bake for 25-30 minutes until the quiche is golden and set, with a slight wobble. Serve with a green salad.
