Last week I made a ginger and pear pudding, a banana bread, a roasted gammon (for dinner the next night and lunches), a sausage and root veg tray bake for dinner and a cauliflower cheese with two extra family portions for the freezer. It all went into the oven at the same time (gammon the longest other bits in and out) I cooked so much food and I wasn't in the kitchen for 3 hours and my 5 year old helped with the banana bread. If I've got my oven on I'm making the most of it.
Today I did a chilli with lean beef mince, peppers, mushrooms , kidney beans etc 8 portions and a chicken curry 8 portions, because if you're chopping peppers, onions, crushing garlic etc you may as well double up and make two different dishes. I was in the kitchen and an hour then left both to simmer for a couple of hours. Gas hob didn't cost much at all. We had chilli tonight and will have curry tomorrow, so tomorrow I will cook some rice and steam some tenderstem broccoli, ping the curry and dinner is done.
Later in the week when we've got a busy evening we will have chicken chasseur from the freezer for dinner, made a couple of weeks ago, with new potatoes green beans and whatever other veg I've got in the fridge. The potatoes and veg take 20 minuted and minimal effort, the hard bit is done.
It's definitely worth cooking from scratch it tastes better, the protein content is usually higher so it's more satisfying and it's not full of salt and sugar.
