Typically the meat I buy each week would be 2 chicken breasts, 500g lean beef mince, 500g chicken or pork mince and then maybe some sausages, or steak, or lamb chops or roast or whatever.
I then buy fruit and veg which is usually something like banana's, apples (whatever is cheapest, we don't have a firm favourite) pears, mangoes, kiwi, passionfriut, mandarins, carrots, capsicum, cauliflower, broccoli, snow peas/ beans, lettuce (I buy mixed in the bag although it's more expensive, but a whole iceberg lettuce doesn't have the same nutritional content AND we never finish a whole one), celery, onion etc. It may vary depending on season and what I have planned for meals. I usually buy enough veg to last a fortnight, but fruit is a weekly re-stock.
We also use a lot of eggs (I love scrambled eggs, I use them for baking and omelettes are good to use up veg at the end of the week).
Bread- Coles bakery is the best- you know it's fresh, and as far as I can see there is no 282 or similar in it.
I buy Pauls (I think?) milk because DP refuses the stuff that was on ACA recently (I can't even remember what all the hoo-haa was about- but the ONE time he watches ACA and he finds out about the milk and so I'm back to paying $3+ a litre!)
We snack on baked goods, made at home. Lots of rice crackers with salsa, the Coles brand fruit/cereal bars for the boys, yoghurt etc.
If I was to be honest, some weeks I don't buy enough food for all of us.. but it's important I keep it to the $150 max per week, or we'll be toast. I would rather go without and let the boys eat than indulge in something like Tim-tams and then not be able to pay other bills etc.
ETA- of course I remember after submitting the post- the milk fiasco was all about permeate. So we buy permeate free.
