Chicken Fricassee with Porcini Mushrooms, White Wine and Tomatoes

This was really yummy.  Unfortunately, the frying part coated the stove and all its surroundings with oil.  I'm just not sure it can be avoided.  I also cooked the chicken a little too long, so it was a bit dry.  But overall, it was fantastic.  I used four large chicken breasts, each one cut in half.
