Add 4 ounces Kataifi (shredded fillo dough) to a large bowl and crush into fine pieces about ½-inch in length (I find it easiest to do this with my hands).
Melt 3 tablespoons salted butter over medium-low heat in a large skillet and add the kataifi.
Reduce heat to low and stir often until golden brown.
Using the bowl the dough was just in, add 7 ounces pistachio cream, 2 tablespoons tahini sesame paste, and ¼ teaspoon salt to a medium bowl and mix together.
Pour the toasted kataifa into the pistachio mixture and stir until evenly coated. Let sit to cool while you prepare the strawberries.
Wash and dry 21 strawberries. Set 3 whole strawberries aside. Cut the stems off the remaining strawberries and cut them into quarters. Add 12 quarters to the bottom of three 12-ounce cups or two 16-ounce cups.
Melt 5 ounces dark chocolate melting wafers at 30-second intervals, stirring between each one until fully melted. Drizzle one tablespoon of melted chocolate over the strawberries in each cup.
Sprinkle some of the 2 tablespoons chopped pistachios over the drizzled chocolate.
Add 2 scoops worth of the kataifi mixture on top of the pistachios and gently press it down to reach the sides of the cup.
Repeat this process with another set of layers.
Dip the 3 reserved strawberries in the remaining melted chocolate and place on top of the cups. Drizzle the tops with the remaining chocolate, then sprinkle on the remaining crushed pistachios.
