there is no medal for chopping your own tomatoes
I think @BestZebbie is right. Most of us need some level of convenience, but we can have that convenience while also mitigating the impact of industrial food on our families.
For eg, pick the jar with the least ingredients you don't have at home. Avoid preservatives, emulsifiers, antioxidants, thickeners in ready meals.
Don't buy supermarket bread, or even most 'bakery' bread. Anything with more than flour, yeast, salt, water is bollocks.
Wraps are almost universally shite (apart from Crosta and Mollica and some from 'ethnic' bakeries if you live in a multicultural area).
And there are still loads of other ways to save time:
Frozen garlic cubes (Asian section of Tesco etc), frozen onion, frozen chilli - don't bother with other frozen herbs. Passata. Most spice pastes for curries/mexican/mediterranean food. Spice mixes in packets. Pouches of grains and rice with flavourings - almost all with no additives. 'Ethnic' sauces but check the ingredients list - it's totally random which companies choose to add crap to (for example) soy sauce.
Generally organic tins and jars are slightly more expensive but completely fine in terms of UPFs - I'm on a tight budget and weirdly I've found that if we make one more tinned rather than 'from scratch' meal per week it evens out the extra cost of organic, if that makes sense.
If you ever fry onions, fry double or triple the amount and freeze.
Have herbs in the freezer.
Have a mini food processsor on the counter all the time to chop garlic, chillis and herbs.
If you're vegan stick to Vivera ready prepped 'meat' (so cheap! So good!).
Even if you're not vegan, following a few vegan cooks on IG is really helpful in making you realise that actually, a lot of v tasty meals are so bloody easy once you've got a few 'exotic' ingredients in.
Again, for non-vegans - I want to tell you how delicious this is: put pasta on to boil, cook frozen cube of garlic and red chilli on low in olive oil for 7 mins, then add prawns and parmesan. Drain pasta, mix, serve.
Organic bottled lemon and lime juice - we get through one of each every couple of weeks - the salt/lemon combo makes almost anything from scratch taste better.
Miso - makes everything taste better.
And as I said earlier - learning how to make sauces without looking at the recipe changes everythign. So for eg: a chinese stir fry sauce, a vietnamese or thai stir fry sauce, a curry sauce, a pesto, an italian tomato sauce.
