We spend £50 a week at Lidl for 2 omnivore adults (I'm 5'9 and DH 6'2 so we are not tiny eaters) and a cat for all food/household/toiletries/cat food/litter/everything really etc. That includes a bottle of gin (£12) and tonic every two weeks and a bottle of wine (£4.50 - £5) most weeks. I am very frugal though and focussed on getting the most for our money. We shop once a week, no top ups.
I do pick up some stuff on Olio sometimes if I can but it's only about once every two weeks and is usually just bread and maybe a bit of veg.
We usually eat Lidl weetabix (DH) or porridge with golden syrup (me) for breakfast. I usually have something like a sandwich or egg/beans on toast or leftovers for lunch and my OH has a cold meat and mixed bean salad (he does weight lifting so this is his choice, something to do with protein).
For staple dinners we have things like roast chicken (I always buy the heaviest "medium" chicken in Lidl for £4.25 as they vary in weight by about 500g) then cut the raw bird in half and roast half at a time. We have the half a roast chicken as one meal with veg & homemade gravy or salad and then I strip the rest of the meat for something like a curry/thai curry/casserole/sweet & sour chicken/chicken fajitas/chicken pie. So I get 4 good dinners out of one chicken for example.
Or we have things like spaghetti bolognese, pasta bake, burritos, chilli, smash burgers (I buy the cheapest 25% fat Lidl mince for £3.10 for 500g and generally use a quarter at a time for a meal for two people).
I also buy the Lidl cooking bacon at £1.99 for 1kg (if you pick through the packs there is usually one with good slices rather than big chunks in, sometimes it is just all streaky slices which is great, but sometimes it's gammon so if you wanted that it's a good way of buying it. I split that in to quarters and a quarter is enough for either a pasta dish like a carbonara or for our bacon sandwiches at the weekend.
We don't buy much branded stuff I suppose generally because it's more expensive and we find Lidl's own is so good. We use lard instead of oil for roasting/frying which is very cheap at 50p for 250g. We only use butter (no spread). I only buy whole milk (3 x 2L bottles a week). I buy coffee beans (we have a grinder and espresso machine at home) from lidl at £10 for 1.2kg). We always have some chocolate (I like Dairy milk so try to get as close to £1 per 100g as I can, I currently have some chocolate coins from Christmas that I bought reduced) and sweets (DH likes jelly sweets so I get Lidl's own) in the house. I buy the 24 pack of toilet rolls for £5.99 from Lidl because it works out the cheapest.
I try never to throw anything away, we either eat leftovers or repurpose them. For example I made a big cauliflower cheese to go with our roast chicken last night, that will either get saved to go with the next roast or blended down into a soup we'll have with homemade bread (I have a breadmaker which makes bread for pennies, I buy yeast sachets in Lidl and regular plain flour as I found it works just as well as strong flour and is half the price). I still buy some sliced bread for bacon sandwiches, why does it have to be sliced bread for these? It's just not the same without.
We also do Lidl plus and when we get a free item I try to get one of the more expensive items in that class. So for the free veg item, the best value thing you can buy is a 7.5kg sack of potatoes for example. I have had free razor blade refills/car screenwash/etc in the past which have saved £4 each instead of perhaps 40p if you bought the cheapest item the voucher would count against.
If I see a good reduction on a non perishable item then I'll buy it in bulk so I currently have 3 x 40 wash boxes of Daz powder (more than a year's supply for us) in the cupboard because I noticed them half price. I colour my roots every two weeks because I hate seeing the grey at home. I use Derma V10 colour which is £1.10 a box and I buy the whole year's supply of 26 boxes at once from Wilko so then I don't have to think about it restocking very often.
We probably have a takeaway every two weeks ish, usually Dominos or fish and chips on which we spend £20-£25. Even then, the Dominos we usually get a large pizza, a garlic bread and a chicken side (use vouchers to get at least 40% off) and that will often provide two dinners, the second one with salad and maybe chips added. At the fish and chip shop we share a fish and a large chips and 2 jumbo battered sausages. If we have chippy chips leftover I always freeze and reheat them later.
