Cooking doesn't get much easier than this. It only takes about 15 minutes to make, but effortless doesn't mean tasteless. Often found on kids' menus, the Classic Grilled Cheese Sandwich is adored by children and adults alike for its mild flavors and ooey-gooey goodness. It's usually made with American or cheddar cheese and white bread. For a healthier version of this comfort food, substitute butter with olive oil or margarine. Or you can skip it altogether; just toast the bread in a skillet on a lower temperature so it doesn't burn. You may also want to use whole-grain or wheat bread rather than white.
