translates as uncouth salad. In Palermo you can buy all ingredients in one single shop: a greengrocer. They sell boiled
potatoes and beans. They are boiled in marmites and have a particular (good) taste.Adding ingredients is not considered cooking. Hence it is 'vastasa', not putting great effort in cooking. Insalata vastasa is a summer salad in Sicily. But don't let that be deterrent for having it in other seasons.Regarding the vinegar, be careful. Better use a little less. Or a sweeter vinegar. Served with bread, this insalata can easily become lunch or dinner. Actually, an excellent lunch during a torrid day.
