1 (3 ounce) package lemon flavored Jell-O mix
1 (3 ounce) can sliced fresh strawberries
1 (3 ounce) can sliced cherries
1/4 cup lemon-lime flavored liqueur
1/4 cup lemon-lime flavored carbonated beverage
In a small bowl, mix the gelatin and strawberries. Fill a large plastic bag with ice, and pour the liqueur over the top, adding more lemon-lime soda if necessary to make the cocktail lighter.
Stir the lemon juice and lemon-lime soda into the gelatin mix along with the sliced strawberries. Chill in refrigerator until serving.
