Pumpkin Cake Roll

3 eggs
2/3 cup canned pumpkin
1 teaspoon lemon juice
3/4 cup all-purpose flour
1 teaspoon baking powder
2 teaspoons ground cinnamon
1 teaspoon ground ginger
1/2 teaspoon nutmeg
1/2 teaspoon salt
1/2 cup chopped nuts
Powdered sugar
1/4 cup margarine, softened
2 (3-ounce) packages cream cheese, softened
1 cup powdered sugar
1/2 teaspoon vanilla

Preheat oven to 350 degrees. Line a 10 x 15-inch jelly roll pan with parchment paper, grease paper, and set aside.
In a large bowl, beat eggs with an electric mixer until lemon colored. Gradually add sugar. Stir in pumpkin and lemon juice. In a separate bowl, sift together flour, baking powder, cinnamon, ginger, nutmeg, and salt; fold into egg-pumpkin mixture. Pour batter into prepared pan, smooth out top, and sprinkle with chopped nuts. Bake for 15 minutes.
Lay a clean kitchen towel out on the counter. Sprinkle powdered sugar on kitchen towel. Turn the warm cake onto towel and remove parchment paper. Roll up cake and towel lengthwise. Cool in refrigerator or freezer.
While cake cools, beat margarine and cream cheese together until smooth. Beat in 1 cup powdered sugar. Add vanilla. Unroll cake and spread with filling, then roll up again. Wrap roll in plastic wrap and refrigerate until served. Cut roll into 1-inch slices.
