We have a 5 day menu plan for M-F. Saturday nights are anything goes, and Sundays are always a roast of some description. Lunches are accounted for and I do my shopping online so it all gets delivered, except the joint for the roast which comes from the local butcher.
Monday is usually soup day- one of the DC does a cooking club so the kids don't usually want a big dinner.
Tuesday- usually a meat day.
Wednesday. Always fish. On the menu at the moment is salmon, rice and veg, kedgeree, tuna pasta bake and something else I can't remember.
Thursday. Slow cooker day as the kids have an activity that doesn't finish till 6.30 and I haven't got time to cook afterwards. Chilli/stew/chicken fajitas type of thing. I do all the meal prep in one go in old 2l ice cream tubs lined with a bag. On the morning all I do is take the meal out, take it out it's bag and straight into the sc on low for 10 hours or so.
Friday. Freezer feast. Chips/pizza/nuggets type thing.
Milk, I buy 10x2l bottles and freeze 8 of them. Take one out of the freezer and put in when the bottle in the fridge gets opened.
Wrt the shopping I have an ongoing shopping list of the things we buy every month without fail. Easy to add it to an order. Then there is a shopping list stuck on the fridge that works on a 'if you've used something then write it on the list basis'. Takes about 20 mins to do the shopping from the comfort of my own armchair.
Monthly spend around 200/250 depending on what needs buying. Yes, I could get it cheaper by going to the likes of Aldi but dc1 is a (legit) dairy free coeliac and Aldi's ff range isn't great. Dc2 has special needs and the thought of attempting to do a monthly shop while they are having a nother fuckingmeltdown in the supermarket ain't a happy one and actually I have better things to do with my time than traipse around endless supermarkets.
