Cook a stew up, grab whatever veggies you want, (I use potatoes, onions, swedes/turnips, carots & random stuff) the cheapest piece of meat you can find, lamb/beef works well, cut everything up into medium sized pieces, as big as you want. Throw it in a pot with vegetable stock - the stock cubes work quite well, make sure you do have stock in it, otherwise it will be fairly tasteless, put water in the pot to just cover everything and bring it to a simmer. At some point add 1-7 or so tablespoons of flour in, depending on how thick you want it and how many veggies in. The best way to put the flour in is to put the tablespoons in a cup, add Cold water, stir it until it's mixed - should be very thin, then just pour it into the stew. Cook it for an hour or so, or as long as you want. Should be nice and do you 7-8 meals... again depending on how much you cook, goes quite well with toast and you can freeze it and eat it later.
Very cheap and quite nice meal.
