In a large bowl, beat together egg, milk, water and oil. Beat in flour, sugar and salt until smooth.
Heat a medium, nonstick skillet over medium-high heat. Place a ladleful of crepe batter into center of pan, tilting to coat the bottom. Cook until golden brown on one side, turning once, 2 to 5 minutes. Continue with remaining batter.
In a small saucepan over low heat, melt chocolate chips, stirring constantly. Remove from heat.
To assemble, spread some melted chocolate on the lighter side of one crepe. Place a line of overlapping strawberries down the center of the crepe and roll it up. Top with whipped topping and drizzle with a bit more chocolate. Repeat with remaining crepes.
