I'm fairly sure real english ale counts as a super food, especially if it comes from a micro brewery, but you only get the full benifits if you grow a huge beard and talk about steam trains
Personally I'm sticking to cider for my tipple of choice on the once or twice a year I drink.
On the meat front though, UK meat isn't too bad, lamb is pretty much always grass fed, make a shepards pie with a root veg mash - that is propper tasty and cheap, free-range chickens aren't too bad either, you can get a decent sized one from aldi for a fiver, and that should do you a roast, half a weeks worth of lunch meat and a soup - just chuck in some leeks, carrots, and owt else not too bitter that is cheap and your sorted.
I'd get dozen eggs or so to go for breakfasts, and get some smoked salmon trimmings from sainsburys or asda - 99p, make with scambled eggs to get some fish in your diet, along with maybe a tin of makrel for lunch once a week.
We don't do any organic veg or meat, just can't afford it (I was far better off living on my student loan )
I can feed a family of 4 for between 60 - 80 quid a week depending on what meat is on short date that I can stick in the freezer so it's do-able on a tight budget.
