Cereal bars with wheat bran

We put in a saucepan or pan, the cereals, nuts, and brown sugar and we cook for 3-5 minutes. We remove from the fire and we add the honey and the essential oil while stirring well. We put the mixture on a baking sheet, cover it with another baking sheet and roll it to the desired thickness and then we engrave. It is good to spread them with oil so the mixture does not stick o our hands. We wrap the bars on a membrane or on non-stick paper and we keep them in a cool place.
