Pour 2 cups of boiling water over top a ½ ounce of dried porcini mushrooms in a medium-sized bowl and let them sit for 20 minutes. Finely strain the mushrooms and reserve ½ of the liquid.
Rinse the mushrooms well under cold water and then squeeze out as much liquid as possible. Roughly small chop the mushrooms. Season the chicken parts well on all sides with salt and pepper.
Heat the olive oil into a large rondeaux pot over medium heat until it begins to smoke likely. Add chicken parts and brown them well on each side, which takes about 4 minutes per side.
Remove the chicken and set aside. Next, add the onions, celery, carrots, garlic, and mushrooms to the pan and sauté for 6 to 7 minutes or until browned over medium-high heat.
Deglaze with the wine and cook over medium heat until the liquid is almost gone, which takes about 5 minutes. Pour in the reserved porcini mushroom liquid, tomatoes, herbs, salt, and pepper and stir.
