You are aware that your diet is not the healthiest and that cooking from scratch would probably be better, but you fear that your kids won't like what you cook and that it will end up in the bin, wasting precious resources you can't spare. You also worry that you will mess it up, so it will taste awful and again it will end up in the bin. You google a recipe and find that the recipe
calls for lots of ingredients you don't have, like herbs or spices. The cost per portion might be low because you only use a tiny amount but can you afford the initial outlay for all the ingredients, knowing that if everyone hates it or it goes wrong, you won't make it again
This was me while my children were small. I wanted to cook nice things, I knew they probably wouldnt like it and I was on a very limited budget and importantly in fuel poverty. Its lovely to make something like a nice hearty, meaty casserole, but I could not put the oven on for as long as it required. Cheap meat needs longer cooking, I couldn't afford expensive meat. Plus one child would say no carrots, other child would turn nose up and not eat it. I did a Sunday dinner for years, I went without to make this Sunday dinner. One day one child wanted a roast potato and some gravy, the other wanted stuffing and some roasted onions. That was the end of my cooking Sunday dinner. I couldn't afford to keep wasting food like that.
From that day on they got a lot of microwave meals or baked potatoes with filling or omelette. Cheap, easy, quick to cook, use not much electricity.
Do I feel bad, yes to some extent, but at least they were fed and I didnt get into more debt with my electric bill or waste lots of food.
