@Frequency Sorry if I'm repeating others, but I've not yet read the thread, just some of your 1st posts.
My tips, if they're any use to you, are as follows:
I substitute a lot, so I might swap eg, mozzarella or parmesan for strong cheddar, if I don't have any in.
I tend to keep the dried tub of hard cheese in, as it keeps well, and will substitute that if it's available. For many recipes, it's the cheese flavour rather than the type of cheese that really matters, so where possible, I will use what I already have.
Again, with oil, I use vegetable oil rather than olive oil as that's cheapest, and it is usually rapeseed, which is good for you. I would only use olive oil on a salad dressing, so it lasts a long time, and that way I can buy it when it's on offer.
I tend to buy what's on offer, and adapt recipes to suit/fit.
So for your meals this week, to save on the cost of jarred peppers, I'd have bought a large bag of cooking peppers (making sure they're not all green), and I'd have roasted 1 in the air fryer for the penne dish. I would then use the rest in the other meals.
For the chicken, I'd have bought some boneless chciken (on offer) for the wrap meal (which allows 1 wrap oer serving on that app). You bought 2 packs of 8 wraps, so more than enough for several meals and lunches.
If the recipe states 640g and my 2 packs add up say 800g, I'd either freeze the extra or use it for lunches or a soup or something.
I also tend to add less meat than suggested and bulk it out with a few more veggies, so in this case I'd use, say 550g chicken, and save the rest for another meal.
I buy spices in the world food aisle or in Asian supermarkets, as they're much cheaper and you generally get more for your money.
I have an extensive collection of herbs and spices, but if I don't have something I'll substitute it for a similar flavour. If you're not sure, you can type it into Google and it will give you alternatives. Eg, lemongrass substitutes
I will also buy cheaper cuts of meat eg, chicken thighs, rather than fillets, or I buy in bulk/when on offer and freeze in portions. For example, our local butcher sometimes sells 5kg of chicken breasts on offer for £25, so I'll buy that and then freeze them in bags of 2, ready for use.
I'll also substitute say, beef mince for pork or turkey mince, which is often cheaper. Same for any veggies in a recipe. I'll try to use what I have rather than buying a particular veg just for 1 dish.
Also, if you can shop around, Asda isn't always the cheapest. I've attached what a lot of these items cost at Aldi atm, and not including the collect fee (which I wouldn't use as I'd go there and shop myself) it comes to just under £36.
I'll have a think and share more tips later.
