Definitely prefer green beans and corn frozen, but from Publix, the green giant brand.the green beans have almond slices and the corn has a sauce that tastes so good. Highly recommend trying these and seeing what he says about it. Other than that yes frozen mixed veggies for my fried rice or shepherds pie. Only canned veggie we eat is peas and that's only because we can't find a frozen one that tastes good.
He has a valid reason...
My husband is the same 😩 No changing his ways lol but I prefer frozen
