The meal served after an argument asks bodies to accept something before words have settled anything.

Eating together after a fight asks the body to make peace before the argument is settled. Passing dishes, sitting close, doing the ordinary shared things reintroduces a physical cooperation that the words have not yet reached. It is genuinely useful and it can also paper over something that still needs saying.

So let the meal do its work without treating it as the resolution. Sit down, eat, let the temperature come down, and then return to the actual thing when both of you are steadier. The trouble comes only when the shared meal becomes the substitute for the conversation, which is a very easy habit for a household to fall into.
