I'm in the process of getting our food budget back under control at the moment. 2 adults and a 16 year old plus cat.
I started by going through the cupboards, fridge and freezer and making a note of everything we already had in. I don't like over buying, but I do keep a store cupboard, so if I open a jar of jam, I have an un opened one in the cupboards and when I open that one I will buy a new one.
I do a monthly shop where I buy store cupboard stuff, freezer items, toiletries, cleaning products, pet food. I use a combination of aldi, tesco and costco for that. £120-£150 per month. I then do a weekly shop for fresh stuff £40-£50 per week. I try and buy seasonally as much as I can.
I do a loose meal plan, so this week is
Sun- sausages
Mon - pizza
Tue - curry
Wed - savoury mince
Thu - pasta bake
Fri - fish
Sat - burgers.
Everything has plenty of salad or veg added and appropriate carbs be it potato, bread, pasta or rice.
I freeze any leftovers for freezer tea, we take lunches to work / school.
One thing I do try and do is make sure portion sizes are right. So I allow 100g of meat per person and ensure that I portion it up before it goes in the freezer or in the meal. I bulk things out with veg and lentils to make it go a bit further and if a recipe is for 4 people, when I am dishing up I serve 4 portions. 3 on plates, one for the freezer.
We do not really snack here, crisps and cakes are part of a meal and we have fruit and yoghurt most times for dessert. I always have baking stuff in so if ds or dh want something they can always rustle something up.
I track the price of everything, the act of writing down what we are spending helps me to keep on track and also allows me to see how supermarket prices are moving. (Increasing at moment)
Our bills are starting to come down again now and my grocery bill including toiletries, cleaning and pet stuff is around £350 per month, which works out at just under £30 per person per week. I could reduce that if I needed to, but at the moment I don't!
