The NBA player Terry Rozier grew up poor and famously shared his favorite sandwich recipe: white bread, spaghetti pasta, table sugar and ranch salad dressing.

The Los Angeles Rams running back Wendell Tyler said he was poor and grew up on sugar sandwiches.

I remember dialog from a very old film, (The Bowery Boys?) that was something like this:

Hey Ma, give me some bread and butta.   We ain't got no butta.   Then bring me some bread and sugga.

Yup, that’s what it made me think of, too.

Rubber Biscuit by the Blues Brothers comes to mind.
