In the same skillet over medium heat, soften the vegetables for 4 or 5 minutes. Add oil if necessary. Season with salt and pepper. Add the wine, herbs and nutmeg. Bring to a boil and reduce until almost dry. Pour over the chicken. Close the pumpkin by setting
the top in place. Wrap the stem with aluminum foil. Oil the outside of the pumpkin. Bake until the chicken and the rice are cooked, about 2 hours, 40 minutes (depending on the size of the pumpkin). Adjust the seasoning.
