The Old School RuneScape Wiki also has an article on Veg batta.

A Veg batta is a type of gnome food that can be made with the Cooking skill. It can also be purchased at the Gnome Restaurant.

Making battas requires at least level 25 cooking. To make a veg batta, mould a batta from Gianne dough. Bake it, then add an onion, two tomatoes, a cabbage and some dwellberries, then bake it again. Add cheese and bake it again. Finish with equa leaves.
