Collaborative Editing for Restaurant Menu?

Hello! I am a graphic designer and one of my ongoing clients is a small pizza and oyster bar. I designed their identity and their menu when they opened last year.

One thing that is unique about this restaurant is that their menu changes frequently (weekly at least) because they offer locally sourced menu items from nearby farms, etc. So far I have been just making the updates for them in my document in InDesign as needed. But apparently the chef has requested a way to update the menu themselves, so that they can do last minute changes as needed.

I am fine with this in theory (I have other clients and often can’t update immediately) but I’m not sure how best to go about making them a document they can update themselves, but that I can still oversee.

I doubt they could navigate an InDesign file, and also there’s the problem of them going rogue with the file.

Canva seemed like a good option, but their type functions are still so basic, it really can’t handle something with as much type detailing needed as a menu. I could redo the menu very simply, but that would be sad, lol.

Does anyone have any good ideas or software workflow suggestions for how to solve this?
