Honestly, unless they change food healing and the rest system, you really don't need a cleric at all
But the problem with that is that eating food is a bonus action, you can do it as much as you want, and healing spells cost precious spell slots. 5e does have the problem where heals are usually only worthwhile to bring up someone who is Downed, but that doesn't mean that eating food should be a more powerful heal than something which costs a precious Spell Slot resource.
