Thanks for the replies!!
Googling a few of those recipes they look much more involved than my usual go-to dinners.
I already have a multi-cooker and it makes amazing risotto and fried rice. I also already use it to make bolognese, casseroles and soups in big (4-6 family meals) batches and freeze as we have a chest freezer.
Plus a food processor and quite a few other gadgets.
I'm thinking I might try (TRY!) to teach DH some of my tricks for getting dinner sorted a bit more efficiently first, then revisit this idea if he's still really struggling.
