Green Angel Food Cake

1 pkg. angel food cake mix
1 pkg. (3 oz.) lime flavored Jell-O

Prepare cake mix as directed on the package, gently folding Jell-O into one-third of the batter. Alternately spoon batters into a ungreased 10 inch tube pan, Zigzag spatula through batters. Bake on lowest rack according to package directions. Turn pan upside down over funnel or bottle to cool completely. Remove from pan; frost top and sides, and garnish the top with lime slices, if desired. Chill well.

1 pkg. (3 oz.) lime flavored Jell-O
1 cup boiling water
1 container (8 oz.) frozen whipped topping, thawed

Dissolve Jell-O in boiling water. Chill until slightly thickened (don't let it get too thick) and blend into whipped topping.

NOTE: can use any flavor of Jell-O.
