Cut the rabbit legs into 2-3 large pieces each.
Clean the onions, carrot and parsnip and cut into large pieces.
In a large pot, sauté the vegetables in a little olive oil, then add the meat, bay leaf and rosemary.
When the meat has browned on all sides, pour in the wine, let it reduce for 1-2 minutes, and then add the diced tomatoes, salt, pepper and cinnamon.
Add 2 cups of water and simmer over low-medium heat with the lid on until the meat starts to fall off the bone.
For the polenta, boil the water with salt and add the cornmeal flour. Once cooked, leave it to cool.
Before serving, slice the polenta and fry it on both sides in a hot pan with a little oil.
