Combine the cream cheese, cheddar, cooked bacon and green onions in a small bowl, set aside.
Wash mushrooms and remove the stems. I like to use a metal 1/2 teaspoon to hollow out a little more of the inside of the mushroom but that is optional.
Stuff the mushrooms with the cream cheese mixture.
Heat a grill to medium high heat (375 degrees F) using a grill pan or grate add the mushrooms to the hot grill, close and cook for 10 minutes. After ten minutes check the mushrooms and cook in additional 2 minute increments until they are tender and the cheese has melted.
Notes
You can use a disposable foil pan, but I reccomend using a grill safe pan or grate with holes in it. This prevents the mushrooms from getting soggy and seals in the best flavor.Net carbs are 2.5 g per serving
