If the dish was just potatoes and onions, you could caption it like:
My nana said she ate potatoes and onions all the time growing up. I’d never thought such a simple dish could be so good, but I absolutely loved it!
Or:
A simple meal from my nana’s childhood: potatoes and onions. I’d never had it before, but it was surprisingly delicious.
Potatoes and onions have been a staple comfort food in many families because they’re inexpensive, filling, and flavorful. Fried together in a skillet, the onions become sweet and the potatoes develop a crispy exterior with a soft center. Many people grew up eating some variation of this dish, especially during times when simple pantry ingredients were the norm.
