Eat a Cold Meal

No plans for dinner yet? Instead of cranking up the stove or the microwave tonight, try eating a meal that requires nothing more than coordination and muscle power. It might be fun to get creative with sandwiches and cereal.
Real Simple also has a complete list of no-cook food (and a great website). Not only will it be a fun experience and make you popular (maybe); by eating a cold meal, you’ll save about a dollar and keep four pounds of coal in the ground. Do the math and in a few months you’ll save a mountain or two.
