Wash the limes. Cut 4-8 lime slices for the decoration and set them aside. Wash and dry the strawberries. Remove the stems. Pick 4-8 strawberries for the decoration and set them aside. Cut the remaining strawberries into smaller pieces. Divide strawberries, mint leaves, and sugar into four glasses. Use a muddle or the handle of a wooden spoon to gently crush the ingredients at the bottom of the glasses to release their flavours. Squeeze half a lime into each glass. Fill the glasses with crushed ice and top up with the lemon-lime soft drink. Garnish with mint leaves, strawberries, and lime slices.
