Over the last few years, as my wife's condition has deteriorated, I have had to take on more of the household jobs, and cooking is one of them. It's been a steep learning curve. I have never had any instruction, it certainly was not offered when I was in school - at the school I went to the girls took cookery while the boys had a choice of woodwork or additional sports (I chose the woodwork).
I can do a roast dinner, but I would be the first to admit that I take a lot of short-cuts. I buy chicken breasts or turkey breast steaks or pork chops. Aunt Bessie's Roast Potatoes, Sainsbury's prepared carrot batons, fresh broccolli (it goes in the microwave) and Bisto Best gravy granules.
Perhaps not the best diet, but we both seem to be thriving
