Just a quickie convenience food that is as retro as it is modern. (note the expensive versions in your freezer case)

1 80z can crescent rolls
2 cups mushroom slices
1/4 cup margarine, melted
Grated Parmesan cheese
1/4 tsp marjoram

Separate dough into triangles. Place on ungreased 12 inch pizza pan. Press out dough to fit pan. Toss mushrooms with margarine. Arrange on dough. Sprinkle with marjoram and cheese. Bake at 375 F. for 20-25 minutes.
