The present invention relates to a cooking apparatus, typically for microwave ovens and the like, that has separate compartments for different foods or food components. These separate compartments are such that food components are kept separate during storage, prior to cooking or heating, as well as during cooking or heating, avoiding unwanted mixing of the food components. The apparatus includes compartments configured such that steam, generated by the heating of a food component in a lower compartment is used to steam cook or heat a food component in an upper compartment.
