Take an 8oz glass and, into the bottom, squeeze the juice of one key lime, straining the seeds. Toss lime wedges into the glass. Add 1 heaping tablespoon of the frozen strawberries with their juices. Fill the cup with ice. Pour lemon-lime soda over ice until nearly full. Add one more heaping tablespoon of strawberries to the top of the drink. Swirl. Drink. Repeat.
