Fire up your Big Easy.
Combine the chili, cream cheese, and 1/4 cup of cheddar. Season with salt and pepper, to taste.
Spoon mixture into the center of the mushrooms. Push it in (gently) to fill the cavity. It's ok to mound it up a good bit too.
Transfer the mushrooms to the Big Easy basket and the Bunk Bed Basket.
Place into the Big Easy and cook until the mushrooms are starting to soften, about 15 minutes.
You can add the cheese now and return the mushrooms to the Big Easy to melt it, or remove them, transfer to a platter and sprinkle with more cheese.
