Rabbit is naturally a little tough. What I do is marinate it in Italian dressing for a day, then pressure cook it or boil it until it is fairly tender. Then grill it, and it'll be delicious.

Also, you can cook it in the crock pot with carrots, potatoes and onions for about 4 hours.

Another delicious recipe is to take the rabbit pieces and put them in the crock pot. On top of them put some tomato sauce and lotsl of spices. (oregeno, salt, pepper, red pepper, italian seasoning, etc.) then put a bunch of onions on top and cook for 4-5 hours.
