I made these for a Christmas Party we had last year and they went like hot cakes! Everyone complimented me on them. They are so easy but that does not take away from the flavor! I've cut the recipe back for this posting but you can double or triple it to suit your needs.
Separate the crescent dough into eight triangles and place on a greased pizza pan with the points toward the center. Do not let them touch.
In a small bowl,combine the mushrooms and butter and toss to coat. Spoon the mushroom mixture over the dough. I usually have to take my spoon and place the mushrooms nicely on the dough and even them out so the entire triangle is covered.
In a small bowl add your cheese, garlic powder and Italian seasoning, mix and sprinkle onto of the wedges.
Bake at 350° for 15 to 20 minutes or until the crust is golden and your mushrooms are tender.
