Do you have a good stock of things to turn those items into meals with?
Look at what you have in your list, and what is usually in your freezer / cupboards - what meals can you make?
Based on the above list along, you've basically got pasta and rice in tomato sauce, to do a couple of meals.
No meat, no protein, no veg, no actual meals.
What are you going to eat your gravy with? Your beans with? Your rice with?
Add some packs of chilli mix, kidney beans and tinned green lentils and you have a chilli.
Some tinned chicken in white sauce and tinned veg - a meal.
You can buy dehydrated soya mince in Holland & Barrett (currently buy one get one free) - you rehydrate, then treat as normal mince - so make chilli, bolognese etc
Some smash could also allow you to make cottage pie using your mince (or tinned green lentils make a good mince alternative) plus some tinned veg, your gravy and a bit of passata.
Buy some red lentils, chopped toms, coconut milk and garam masala and you can make a nice dhal. Add frozen butternut squash and sweet potato for bulk. Add frozen spinach for added vits.
I'd add various spice mixes, some jars / bottles of stir fry sauces, kidney beans, tinned green lentils, chopped toms, coconut milk, dried red lentils, dried soya mince, tinned mixed veg, tinned corn, tinned potatoes, more rice / pasta, cheap cereal bars, a few packs of noodles, a few tins of curries / bolognese / chicken in white sauce for shelf stable items, then a selection of frozen veg (sweet potato, butternut squash, spinach, broccoli, chopped onion, sliced onion, sliced peppers).
This opens up curries, stir fries, a few traditional meals as above - more importantly - variety and a decent whack of nutritious food rather than beige staples.
All of this depend son your cooking skill and family preferences though - but on the whole, look at what meals you can make - there's no point having 10 tins of beans and 10 tins of chopped tomatoes but nothing to eat it with! Look up recipes for lentil curries, chickpea tagines etc - try a few recipes out, then shop from there.
Eg - dhal - 1 tin chopped toms, 1 tin light coconut milk, 200g chopped frozen onion, 20g chopped frozen garlic, 10g garam masala, 10g tandoori curry powder, chicken stock cube, 200g frozen spinach, 300g frozen sweet potato, 300g frozen butternut squash. This makes 6 moderate portions. Try it - if you like it, then buy double the quantity and you then know you have 3 meals worth of ingredients.
chilli - 200g frozen onion, 1 pack chilli mix, 1 pack smoky fajita mix, 2 tins chopped toms, 2 cartons passata, 1 tin kidney beans, 1 tin green lentils, 500g mince / mince substitute (dried soya or tesco frozen meat free mince) - makes 8 moderate portions. Scale up as needed.
So if i have 1kg mince or mince substitute, 8 tins chopped toms, 2 tins coconut milk, 2 tins kidney beans, 4 cartons passata, 2 tins green lentils, 2 pack chilli mix, 2 pack fajita mix, 2 bag frozen onion, 1 bag frozen garlic, 1 bag frozen BNS, 1 bag frozen SP, 1 bag frozen spinach, stock cubes, garam masala and tandoori curry powder, i can make 28 portions of tasty and fairly nutritious food. Bulk that out with 2kg rice and you are well on the way - that lot comes to just over £27.
I suggest meat free mince or dried soya mince as it is much cheaper than good quality meat mince.
