The approach to cooking, followed by my partner and I, is:
(a) buy meat when it's reduced, and either cook immediately or freeze, then cook later, which means the prepared meal can't be frozen
(b) cheaper cuts of meat are best for slow cooking, so good value even if not reduced price
(c) same approach to reduced veggies, herbs etc
(d) we use whatever veggies are in glut in the garden - potatoes, parsnips, dried beans (dried so they'll last through through the winter)
(e) some fruits can also be good eg windfall or reduced price apples with pork (don't have to be cooking apples; can cook with eating apples, which are more versatile, particularly for a single person household); dried apricots with lamb etc
(f) rice, pearl barley and red lentils are all cheap, filling and tasty, especially suitable in slow cooked meals
(g) tinned red kidney beans are easier and safer than dried red kidney beans, which take ages to soak, then boil, not really practical for one person
(h) for several months each northern winter, I am effectively a single human household, so cat sometimes gets scraps / fat from meat; also, invite friends round, as it's more fun than eating alone.
So, recipes aren't really needed, just use whatever you like.
