Rim the ridge of your glass with a lime wedge and dip in a mix of margarita salt + sugar + toasted coconut [I used about 3 tablespoons salt to 2 teaspoons sugar and 1 1/2 tablespoons toasted coconut]. Fill the glass with ice. In a cocktail shaker, combine tequila, grand marnier, simple syrup, coconut water, cream de coconut and lime juice with ice, and shake for about 60 seconds. Pour over ice and squeeze in lime slices and add a few strawberries. A slight bit of separation may occur from the cream de coconut, so shake well!
