Hi,   I'd like to provide an array of meals that are frozen and can be quickly heated and served.   I'd like your viewpoint on 3 types of ovens   1) Steam Combi - e.g. Rational selfcookingcentre   2) Convection+Impingement- e.g. MerryChef E2S   3) convection + Microvave e.g. Menumaster   While I think 2&3 are more suited than 1, but would like your feedback. The menu would consist of  Lasagna Pasta Rice Noodle
