Long ago wife and I split cooking responsibilities equally, which worked well. But now (because of my work schedule) she does the vast majority of the cooking. But she is not a good cook so I'm getting tired of eating bad food. But if I give even a single helpful suggestion she gets all defensive. So most days I just make my own food, which works ok because she wants to eat non-vegan stuff sometimes. But god damn you ever eat soggy pasta with half cooked store bought sauce? or you ever had a totally unseasoned taco (I mean she literally just puts some beans in a pan and then opens up some canned tomatoes if I am lucky she'll make some rice)? Because I eat those a lot.
All this to say, any easy way to help wife not suck at cooking? If the answer is no I will carry on making my own food which is just fine too.
