So I had a bit of a dilemma with this as we don't normally eat much tinned food (more likely to go for a freezer stash!) so I didn't want to prep a cupboard full of food that would never get eaten.
So I ended up doing a meal plan for 3 days and doubled it so that we had 6 days worth (I know there would always be enough in the fridge/freezer for the first few days before it turned) so I think we would be ok for about 10 days. We do go camping so have a camping stove so weather permitting would be fine to hear stuff up but I know a few of the options can be eaten cold.
I have only used things that I know we would incorporate into meals in normal times so my next step is to list the use by dates to make sure they don't go to waste...have popped below my plan in case it is of interest! It helped me to feel sane by having an end 'tin' in sight.
Breakfasts:
6 long life milks: oat, almond, coconut
Cereal
Granola
Oats
Lunches:
Baked beans / oat cakes / rye bread (the biona one has a crazy long use by date)
Tins of tomato soup / oat cakes / rye bread
Veg / tofu / cashews / rice packet
Dinners:
Gnocchi, pesto and nuts
Tuna, veg, pasta, tinned toms
Baked beans and sausages and grains (went for the merchant gourmet ones as can be eaten hot or cold)
Fruit: tinned peaches, tinned pineapple, jar of mango
Veg: tinned peas, tinned sweet corn, jar peppers, beetroot
Morale snacks: cereal bars, chocolate, sweets, custard, jelly pots
I ended up looking what was on offer on ocado and they kept doing good discounts on their longer life / tinned foods so have just gone for what was well rated! I found it helpful to do online so didn't end up in a faff in store.
