In a blender, combine 3/4 cup pink lemonade concentrate, 3/4 cup water, half of the strawberries and 1 cup ice cubes.
Pour contents into a freezer container.
Repeat step 1 with the rest of the lemonade concentrate, water, strawberries and ice cubes.
Pour contents into the same freezer container or a separate container if you’d like to divide the batch.
Cover container(s) and freeze for at least 8-12 hours.
Let stand at room temperature for 30 minutes – 1 hour before serving.
Fill chilled glass 3/4 full with slush. Top with lemon lime soda.
If you’re serving this slush indoors, sometimes it’s a nice touch to add a spoon straw.
If you’re serving this outside and it’s a nice, sunny day, plop a fun straw into the drink.
