I wonder if anyone has ever given any thought as to why supermarkets are laid out in the way they are
You walk in and all the fruit and veg and salad is there, so you fill up on these things, then the fresh deli/dairy/ready meal section
Only then do you get to tins and packets and finally to frozen
There is a reason for this
You buy fresh, you're paying more per item for a start, you're more likely for it it go off and then need to replenish
If you fill your trolley with packets of beans, lentils, tinned veg, tinned fruit, frozen veg, frozen fruit, frozen meat etc, You pay far far less, you manage the turn over in the home better
A tin of peaches with some greek yoghurt, easy cheap snack, more protien and more filling than a handful of grapes, which then turns into a handful of strawberries and so on.
Make your own houmous or bean dips from tins of beans or chickpeas, you can freeze this in any case, have this as a snack with pita breads or crisp breads.
