how to fill a gap between patio and lawn

[huma]

What type of fill (soil? topsoil?) would be the best option for filling a cement retention gap between paver patio and a lawn that the grass will grow there? (pictures attached)

I would just use sand.

Sand won't get out of there with wind?

Why do anything?
That gap will help keep the grass from growing into the patio.
