Cook one (just one!) part of dinner.
As food prep becomes more of a habit, and you start to know what's coming up in the days ahead, "try cooking some parts of your week's meals on a Sunday or Monday, to eat throughout the week," says Livingston. Having one staple component ready (whether it's poached chicken, roast pork tenderloin or brisket cooked overnight in the slow cooker, which you can then use in a number of ways) can be just as helpful as having a whole casserole in the fridge, she says. Other ways to ease into preparing meals ahead of time: Cook a pot of brown rice or quinoa. You can use it as a side dish for a couple of meals, or as the basis for an entrée, such as fried rice. It's also great added to salads.
