This was very popular in my house during our childhood, we - my younger sis, bro and me used to mash up the ingredients in ABC soup (usually consist of potatoes, carrots, onion, and tomatoes), stirred in a dash of soy sauce and bit of the soup and we'd eat bowls after bowls of this mashes.
I cooked ABC soup for little girl today as per her request, since I was not free to make her another surprise snack after her pre-school, I just filled up the container with some ABC soup, like below:
just the ingredients from soup without the liquid...
... mashed up coarsely with a fork, added a dash of soy sauce, pinch of pepper and bit of soup, done.
When little girl was in the car after school:
LG: What is my surprise, mummy?
Me: Remember I told u what I will cook for u this morning?
Me: Neh... ur favorite soup ah.
LG: Ooh! ABC soup!
She quickly opened up the container, and scooping non-stop to her little mouth, with her satisfying little voice: "Hmm... my favorite soup...."
