Cybertronian food

Despite being robotic contructs, Transformers seem to have certain substances that are analagous to food. These food articles include, but are not limited to, the following:

• Seasonings like flavorful iron filings, savory mercury sauce, or lead sulfide crystals.
• Cesium salami
• Berylium bologna
• In some rare cases, Energon.

How these robots eat the food is up to debate, because some of them don't have mouths.
