It's not Sunday big family dinners I hate. It's specifically roast dinners.
Firstly every single time we have one (or I eat one somewhere else) I'm ill afterwards. I have no idea what it is but some part of it sets off an upset stomach followed by days of cramps. I'm ok if I just eat the meat and a few veggies but frankly that's not the most exciting of dinners.
Then there's the stipulation of "roast rules", always in the evening not at lunchtime. Invariably being everybody is tired and the DC barely eat anything. Then there's the "at least 2 types of potato" rule (but preferably 3 - roast, new, mash) and "at least 5 types of veg". It's such a palaver.
Last week I cooked roast chicken with crunchy baked potatoes, ratatouille and nice bread - that to me was perfect. Low fuss, minimal clean up. But it's not classed as a proper roast here :(
