I know my granddad was obsessed with his meat and 2 veg dinner although I'm not sure why potatoes are always missing from this title because ALWAYS included potatoes too! My grandparents now in their late 80's do enjoy a variety of dinners but when they come over I always choose to cook a meat and 2 veg dinner for them.
The funniest thing is that, my sons, aged 8 and 6 love curry, fajitas, pizza, jambalaya but they really LOVE the British traditions too; pie, toad in the hole, casserole and steak all served with (of course) a choice of 2 veg AND the potatoes. I get a bit keen and like to add their letters on the top of homemade pies- see the photo (geeky I know).
Have the veg options changed much from my granddad's? We have fine trimmed green beans rather than runner beans. I occasionally roast the carrots (just to be exciting) and sweetcorn is a regular choice for my boys, but I don't think they would make Grandad's top 10 - it was what ever was in season. My grandparents boiled veg and used a pressure cooker for potatoes, I use a hob top layered steamer. (I have heard pressure cookers are making a come back though!).
Meat wise, I might be making huge assumptions as I'm not a food historian but I think my boys eat a lot more meat per dinner and I would like to think it's good quality. When I next see my grandparents I will have to find out more about their diets 70 years ago.
Top tip- start a veg patch, and shop at a veg market to eat seasonal, fresh vegetables.
My grandparents have always had a veg patch and shopped local as it was the only option for them years ago so the Love British Food fortnight values will seem logical to them. We do have a small veg patch but I would say 90% of the time they have no idea where their food is produced or how far its travelled to get to their plate. My plan during this fortnight will be to chat about this during meal times and find out where they think their food comes from. I might have to break my no technology at the table rule as we may need google's help and even get an atlas out!
