I've scored a line through the items that I would consider unnecessary and [xx] around items that you probably wouldn't buy every week.
You can make your own passata by bunging canned tomatoes in a blender.
You can make your own fajita mix far cheaper than buying a packet. Cumin, red pepper flakes, a dash of cayenne, dried coriander, oregano, salt and pepper is all it takes. These items will last you ages.
Does your shop offer large sizes of tinned tomatoes? These are sometimes cheaper per ounce than small tins, and you can freeze what you don't use.
Buy a large tub of vanilla flavoured Greek yogurt and one of plain.
Plain yog (full fat esp) goes in all recipes calling for buttermilk, sour cream, and creme fraiche.
Try to buy frozen veg - peppers, cauliflowers, celery. You can get various frozen veggie mixes in Aldi. Only buy more expensive fruits if they're on sale (like mango). There are alternatives to quorn.
For a home baker, buying pure vanilla is an indulgence. Buy a cheaper option instead.
See if you can buy rice in bulk in Asian shops.
............
Instead of buying items for a specific recipe, start developing a pantry of staples.
Buy tins of tomatoes beans and frozen fruit and veg when they're on sale.
Buy pasta when it's on sale.
Buy herbs and spices for your own flavour mixes, esp when on sale, and check out bulk prices too.
Buy an insulated mug and use water from home with a few ice cubes if you're going to be out and it's hot.

I second the advice to a PP to buy a little shopping trolley to carry stuff home in. You can buy one with an insulated insert or buy an insulated bag separately.
