Preheat oven to 425 degrees. Spray a 8" square baking pan with cooking spray.

Shave cheese in large thin strips. (I use a vegetable peeler).

Sauté shallots in 1 tablespoon olive oil over medium low heat, stirring occasionally. Add thyme or rosemary if using. Cook for approximately 20 minutes til shallots are soft and golden.

Peel pears and quarter them. Remove the cores. Put pears in the baking dish and spread cheese evenly over pear pieces. Bake for approximately 20 minutes. Pears should be a little soft but still hold their shape. Cheese should be starting to turn brown.

While pears and shallots are cooking, prepare dressing and arrange greens on a serving platter.

When pears and shallots are done cooking remove them from the heat and allow them to cool 5 minutes. Arrange pear pieces and shallots over greens on the platter. Serve the dressing on the side.
