Turn the potatoes while doing so. Peas peel, wash and cook in boiling salted water for 5-7 minutes. Quench, drain. Clean, wash and peel the cucumber, if necessary, and cut or slice it into thin slices.
Clean and wash the peppers and cut them into fine strips. Peel and chop the onion. Vinegar and mix with salt, pepper and sugar. Fold in 3 tablespoons of oil. Stir in onion. Mix peas, cucumber and paprika with vinaigrette.
