I've only had peanut sauce once at a Vietnamese restaurant. I can't remember what the dish I had was called, but it was delicious. Like cold meat and shredded lettuce over warm rice? It was a big bowl. I've never had such delicious food. It was a literal hole-in-the-wall place in New Orleans.
That is probably Rama. Usually made with fresh spinach but ohhhh so good!
I said lettuce but meant cabbage.
