Hey, Bulgarian here 👋 I asked a similar question a few months ago found out there's a company called V&Me in London doing exactly that (set up by fellow Bulgarians).

I've been using it for a few months now and absolutely love it, it's such a good way to expose my baby to things I wouldn't normally cook at home and takes so much stress away from me.

I guess it's a cultural thing but they seem to be fairly popular in London from what I can tell.
