My DH is a very fussy eater, though he does not think so. It really does bother me.
He is a real pain to cook for and it is embarrassing when we eat at other peoples homes. When we were first together he asked me to pick up ingredients for a salad, so I did, I did not know that a salad was spinach and avocado only! He will not eat eggs, fish (unless it is smoked salmon) most vegetables, dishes were veg and meat are mixed, olives, tomatoes, anything spicy or with too many herbs.....
I look through recipe books and know that I can not cook most of the dishes.
I have to tell friends his list of food he will not eat and I when we do go to friends for dinner he always complains afterwards, to me. So boring.
His father is even worse, no pasta or rice, nothing with a sauce, nothing that would not have been eaten in a mining village in the 40's. I only ever cook Sunday lunch for him, not pork though and he will only eat the peas from the veg.
DH is away at the moment, so I am having tuna steak and salad for supper, he would never eat that.
I am not bothered about other people being fussy if I am not expected to cook for them daily.
