Place the couscous in a bowl and pour over the olive oil, lemon juice and 50ml boiling water. Cover and allow to soak for 5 minutes, then fork to separate the grains.
Meanwhile, cook the peas in a pan of boiling water for 3-4 minutes until tender. Drain and allow to cool. Stir into the couscous, along with the avocado and dill, then serve in little tubs with some crunchy veg.
