    1. Remove stems from mushrooms and finely chop stems.
    2. Heat olive oil in a pan over medium heat; cook and stir chopped mushroom stems, shallot and garlic until softened, about 5 minutes. Pour wine into the pan; cook and stir mixture using a wooden spoon until liquid is evaporated, 1 to 2 minutes. Cool mixture to room temperature, about 10 minutes.
    3. Preheat an outdoor barbecue for medium heat and lightly oil the cooking grate.
    4. Brush the olive oil mixture over the top each mushroom and place, top-side up, on a baking tray. Mix pesto and pine nuts with the mushroom stem mixture together in a bowl; spoon into each mushroom. Sprinkle shredded cheese blend over the filling.
    5. Cook mushrooms on the preheated barbecue until edges are blackened and stuffing is bubbling, about 10 minutes.

    These are very easy to assemble with few ingredients, making for an impressive looking side dish. At first I thought there's no way there will be enough "stuffing". And there really wasn't much, but I later realized that the amount was perfect. Any more and the mushrooms would have been totally overwhelmed by pesto flavor. I did have a couple issues with the directions though. First, I don't see the need to lightly oil the grate of your grill, since you'll be using a grill pan anyway. In step 4 it says to brush the olive oil mixture over the top of each mushroom, yet there is no mention of any olive oil mixture in the ingredients. What to do? I ended up lightly brushing the mushrooms with some flavored olive oil I had. Next, the directions say to place the mushrooms TOP side UP in the grill pan and then to fill each one with the stuffing. I'm assuming this should say top side DOWN. Aside from a few unclear steps, these turned out very tasty and I will definitely make them again. The only addition I felt these needed were a sprinkle of salt. I would salt the inside of each cap lightly before stuffing them next time. I served these with pork tenderloin and a fresh garden salad. Thanks for the delicious recipe darklordlarry!  -  07 Aug 2014  (Review from Allrecipes USA and Canada)
