Plan a pantry week
Challenge yourself to get through one week every quarter (or more often, if you can) without setting foot in the grocery store, says Mary Hunt, author of "Debt-Proof Living." Use leftovers, unbury freezer items and clean out your pantry. Chances are, you have more food on hand than you think. Use the money you've saved on groceries to pay down debt, bolster your savings or even make a contribution to charity.
