Half-ready vegetables to remove from the oven, remove the foil and put back in the oven on the grill to brown the potatoes. Then take out, lay on top of mushrooms and sprinkle with cheese mixed with garlic. Return to the oven and bake until the cheese is completely melted.While gratin languishes in the oven, prepare a rabbit, or rather, his feet. The foot is best to take the front but also the back is also good.
Wash, dry with paper towels and fry in a slow cooker on the program "Frying on both sides". Cover with mustard and spices, add white wine and simmer on the program "Stewing" until ready. Usually it takes about 20 minutes, but it all depends on your slow cooker.
If done promptly, the gratin will be ready almost simultaneously with the rabbit!
