I grabbed the plastic tubes from Amazon here to make these. They are super easy to make and without all of the un necessary ingredients!
(Yield 5 tubes)
1 cup Plain Yogurt
1 cup chopped Strawberries
1 tbsp Gelatin
Put all ingredients in blender or food processor and blend until smooth.
Using a funnel, fill each tube and seal.
Place in freezer, until ready to place in lunch boxes.
