Lime Angel Food Cake Rolls

1 (16 ounce) box angel food cake mix
2 drops green food coloring (optional)
2 (8 ounce) containers lime-flavored nonfat sugar-free yogurt
Lime slices (optional)

Heat oven to 350 degrees F. Line two 17 x 11 1/4 x 1-inch jellyroll pans with parchment or wax paper; set aside.

Prepare angel food cake mix according to package directions. Divide batter evenly between prepared pans. Draw knife through batter to remove large air bubbles. Bake 12 minutes or until cakes are lightly browned and a wooden pick inserted into centers comes out clean.

Invert each cake onto separate clean towel. Starting at short end, roll up warm cake, jellyroll fashion, with towel inside. Cool cakes completely.

Place 1 to 2 drops green food coloring in each container of yogurt, if desired; stir well. Unroll cakes; remove towels. Spread each cake with 1 container yogurt, leaving 1-inch border. Roll up cakes; place seam side down. Slice each cake roll into 8 pieces.

Garnish with lime slices, if desired. Serve immediately or refrigerate.
