Hack a healthy, yet not expensive, meal.
ichverstehe: I have no idea about food prices in your part of the world, but being a high school student living on a very small budget (think  $200/month for food expenses, and this is Denmark which is relatively expensive) I have learnt a few tricks.One of them is baking your own bread! I have an electric mixer with some special tools for dough, so I spend 15 minutes every two days and have pretty good and cheap bread.Soups are another nice one, forget about the advanced ones, go with something simple, yet good, e.g. potato-leek-soup. Make big portions, put it in the freezer.Basic courses such as pasta can be pretty good if you spice it up a little. Forget about the ketchup, mix up a simple tomato sauce.And a little gem from The Silver Spoon: Some oil on a pan, put on a whole garlic clove untill it's brown, get it off the pan. Add a can of tuna, and some tomato puree that has been mixed with a bit of water. Turn down the heat, give it some fifteen minutes and add to your pasta. Inexpensive, easy and surprisingly good if you spice it up a bit.Basically anything that you can make in big portions and freeze is a bargain.
