Preheat oven to 350F. Thaw fruit & place into an ungreased 9x9 inch square pan. (DO NOT DRAIN!) Sprinkle dry cake mix evenly over fruit until covered. Cut margarine into pats & dot over cake mix. Lightly sprinkle with nutmeg to taste.
Bake in 350F oven about 25-30 minutes, until slightly browned throughout top. Cool 15 minutes. Serve.
