Prewrapped Salad Free Kebabs

Martin Fox's Uncle Frenzied Ferris owned a small kebab stand.

Once he noticed that if he put all his kebabs on display in groups of 3 he would have 1 kebab left.

The same would happen if he put them in groups of 5, 7 or 9.

All of them are on display only if he put them in groups of 11.

What was the smallest amount of kebabs Frenzied Ferris have?
