Well my fridge generally contains these things:
Sauces - tom, soy, worch, chilli
Butter, Eggs (home grown) Milk, cheese, yoghurt
Condiments - Jam, PB, garlic, ginger, chutney
Veges and fruit - salad mix, carrots, cabbage, capsicum, apples, zuchini, shallots, corn
And at the moment has beetroot (tinned), leftover fritters and lasagne.

I shop weekly or fortnightly as I impulse buy lots if I got to the shop everyday, costs me heaps more.
