You are spot on. There's even a local fast food chain "Giraffa's" that serves that - slow cooked food, then microwaved/heated in shop premises and sold as fastfood.

The typical average Brazilian lunch is loaded with overcooked dishes - read: wasted nutrients, dripping with vegetable oil and sugar (fructose and others), occasionally covered with a couple of lettuce leaves and freshly sliced tomatoes.
