Kupat with vegetables in the oven is a very satisfying, aromatic and tasty dish. It is great for lunch or dinner, for cooking you can use any vegetables that you like best, so adjust their amount to your taste or appetite. Kupatas or meat sausages can be used from any meat; there is no need to lubricate vegetables with oil since juice with fat will stand out from the kupatas and this will be enough.
