Passthecake if you'd seen my kitchen inventory you probably wouldn't say that! I really have got into just going food shopping out of habit, it's shocking.
We have a lot of tinned beans of different types, tinned tomatoes, lentils etc in the cupboard, plus a ridiculous amount of grains (pasta, rice, cous cous, quinoa, noodles) so even just with that it'll make a few meals.
We don't buy meat either (DH is veggie, I rarely eat it and never at home really) so that helps keep costs down I suppose.
I'm a big fan of a one-pot meal, it's usually cheaper and saves on washing up!
