When my husband and I met, he didn't cook AT ALL! When I asked him what he ate, he said takeout and pasta with jarred sauces. But, bit by bit he has learned and is quite a good cook these days. He makes his own pasta sauces these days, curry, the other day he made a lamb stew with leftovers from a barbecue we had. He's a big fan of the multicooker as well.

Maybe start off slowly, cooking one weeknight, then on to two nights.
