Season the rabbit with freshly ground salt and pepper.
Peel the zucchini, remove the seeds and slice the remaining pulp.
Peel the onion and the garlic cloves and finely slice them.
Take out the seeds from the bell pepper and dice the pulp.
Heat a deep frying pan (or a pot suitable for frying) over medium heat and fry the rabbit chunks (3 minutes on each side).
Take out the meat on a plate and put the vegetables in the frying pan (zucchini, onion, garlic cloves and the bell pepper).
Saute the vegetables for 10 minutes.
Add the rabbit chunks and the olives.
Add the wine and leave to simmer for 3 minutes.
Add the boiling water and crumble the chicken stock cubes. Boil for 30 minutes on medium heat with the lid on.
Add the lemon zest and the capers and boil for 20 more minutes without the lid to reduce the sauce.
Serve hot with the freshly chopped parsley next to pasta or basmati rice.
