1. Season chops all over with salt and pepper, then sprinkle with thyme and sage.
2. Heat oil in a large nonstick frying pan over medium heat. Add chops and cook 5 minutes, or until nicely browned underneath. Turn chops over and pour in Calvados; cook until liquid evaporates, 2 to 3 minutes. Reduce heat to medium low, cover pan, and cook 6 minutes, or until chops are barely pink in the center (cut to test).
3. Transfer chops to a warm plate, tent with foil, and let rest 5 minutes.
4. Add mushrooms to pan and cook in pork juices 2 to 3 minutes, or until tender.
