I think we are all feeling the pinch with the COL, I certainly am but I manage ok on sticking to SW
I only buy frozen berries - cheaper and more flavoursome and no waste. Im careful with the rest of the fruits I buy, which tbh isnt much. A couple of apples or pears and satsumas so theres always something to reach for, but I buy loose so Im not throwing any away
Ive swapped to a lot more frozen veg, used to be only peas and sweetcorn, now its spinach, cauliflower, broccoli, stew mix and those bags of small mixed veg - the carrots/beans/peas mixes
I buy salad veg a couple of times a week. Just enough that it will get eaten. I also eek it out, like rocket is expensive but nice, so I shred iceburg - cheap and tastless and mix some rocket through it. I dont buy salad onions - brown onions I have will do rightly sliced thinly and using pickles which have a long shelf life helps - pickled beets, gherkins, onions, cabbage - all add variety and all on plan
Tin of tomatoes is 35-40p - thats the base of tomato sauce - no need for jars. If you dont already have a good selection of herbs and spices its worth picking up just one a week. Home bargains/lidl/B&M are cheap and its worth buying garlic and ginger in either paste, jar or frozen form
Meat there is no denying its not cheap and SW concentrate on Lean meat - so 5% mince, all fat and skin removed from whole meat. Even here you can still save. Turkey and Chicken mince is often cheaper to start with then beef mince and I often find it YS. YS skinny burgers dont have to stay burgers, smash them up and make meatballs to feed the whole family. I got a load of packs of 2 at 90p and stuck them in the freezer. Even Jamie oliver has a programme on all4 about meals for a £1 and they are all SW friendly
The SW app has a whole lot of budget meals , and every recipe I have tried from the app has been pretty tasty to be fair. Like no one refused to eat it.
