I was raised in New Mexico, where "breakfast" in a Restaurant was commonly Enchiladas with an over-easy egg on top. (Heuvos Rancheros)
At home, we often had "grits" with our breakfast of eggs and bacon or sausage. Salt and pepper and butter on the grits, AND, if we had HAM for breakfast...then "red-eye gravy" (made with the ham-grease and coffee). (My Folks were Southerners)
Elsewhere, in later years, in a Restaurant, I couldn't get "grits"...only "hash-browns".
One time, when I was visiting relatives in North Carolina, I went alone early one morning to a restaurant in a small town there. I ordered Ham and eggs and hashbrowns.
"You must be from "up North", the waitress said.
"Now, just WHY would you say that?", I responded.
"'Cause only YANKEES order hashbrowns! she said. "Ain't you never heard of GRITS ?"
I laughed. "Gimme Grits, Red-eye Gravy, Salt and Pepper, and some extra butter."
She smiled and figured I must be O.K.
(I forgot to ask her out to dinner......but, I ate BBQ with some "kissin' cousins that evenin')
Ha-Ha!
