Chop the strawberries into small bite-size pieces and combine with sweetened coconut flakes. (Chopping the strawberries makes it easier to cut the tart later on. So the smaller the pieces, the better.) Set aside.
In a food processor, pulse the Oreo cookies to fine crumbs and mix it with melted butter. Press the crumbs mixture evenly into 9-inch tart pan with loose bottom. Refrigerate while you make the ganache.
In a small saucepan, bring the coconut milk to a simmer, remove from heat and pour it over the chocolate chips to make the ganache. Let it sit undisturbed for at least 2 minutes, then whisk the mixture until smooth. (If for whatever reason, you still have solid chocolate pieces and the mixture is cooled too much, simply heat it in double boiler over simmering water until completely smooth.)
Reserve about 1/3 of strawberry mixture for later and spread the remaining mixture evenly in the tart crust. Then pour the ganache. Refrigerate for at least 2 hours to set. Before serving, decorate the top of the tart with reserved strawberry mixture. Serve the tart chilled.
Notes
Store the tart in the refrigerator for up to 3 day, covered.
