Combine the first four ingredients into the Ninja Creami pint container, use a hand blender to blend until smooth.
Freeze the container on a flat, level surface for 24 hours or until frozen solid.
In a small saucepan, combine sugar and strawberries. Heat on medium, stirring consistently until the strawberries become tender (about 5 minutes), mash them with a fork to create a sauce. Allow to cool completely.
Remove from the Ninja Creami container from the freezer, run it under hot water for 30 seconds or leave it on the counter for 10-15 minutes and take off the lid.
Place the container into the outer bowl of the Ninja Creami, then lock the outer bowl lid into place.
Secure the outer bowl into the Ninja Creami machine. Press the Lite Ice Cream button and allow the cycle to complete.
Remove the outer bowl lid. If the ice cream is still powdery after the first spin, then add it back to the machine and press the Re-spin button.
Make a small hole in the center of the ice cream, add the strawberry filling and 1/2 the graham crumbs. Mix again using the Mix-in button.
Top with graham cracker crumbs or fresh strawberry slices and enjoy!
