Drain and rinse the chickpeas under running water, dry them, and season them on their own with black pepper and a squeeze of the lemon juice.
Dice the cucumber, halve the tomatoes and slice the red onion thinly, cutting everything to roughly chickpea size.
Shake the olive oil, remaining lemon juice and black pepper together in a jar until combined.
Toss the chickpeas, cucumber, tomatoes, onion, feta and parsley with the dressing.
Fold in the cottage cheese last, turning the bowl three or four times only. It should look under-mixed.
Taste before adding any salt, then rest the salad 5 minutes before serving.
