Tip the whole tub of cottage cheese into a blender or food processor.

Blend a full 30 seconds, scraping down once, until there is no visible curd and the texture is completely smooth. Stop short of this and the result is stirred cottage cheese, not whipped.

Add the lemon juice and salt and pulse twice to combine.

Fold in the sliced green onions by hand so they stay visible rather than turning the whole bowl green.

Chill at least 20 minutes before serving; it thickens noticeably as it rests and tastes cleaner cold.
