Pour the condensed milk into a large (2 quart) mixing bowl. Use a rubber spatula to remove all of it from the can. Add the cream cheese. Using an electric mixer, beat until well combined, about 1 minute. Add the fruit pulp and beat just until well combined.
Pour the mixture into the pie crust. Refrigerate, uncovered, for at least 3 hours (or up to 2 days, covered). To serve, remove the pie from the refrigerator and slice. Garnish each slice with a squirt of whipped cream, a strawberry, and a mint sprig, if desired.
