I find that the cheapest and easiest meal to make is to just cut up what ever veggies I have in the fridge and stir fry them and serve with rice. If you eat meat, just thinly slice some and cook that first (a chicken breast or a steak can go a long, long way in a stir fry). This is good for those vegetables you just don't know if they're going to make it much longer
(I usually have lots of those). Season with soya sauce or any favorite seasonings. Not really a recipe, but a cheap, easy and versatile meal that doesn't take long to make.
