Unless you've got a a chef in the kitchen, eating well around a busy, chaotic life might seem impossible. It's not. Here's how.
Take one day out of the week for a trip to the market followed by all the prep work. It'll save hours and hours of time later in the week when you're schedule is chaos. Double-up on purchases -- you'll be freezing it later nothing will spoil and it'll save you a second trip to the store later. Once home, tackle everything at once. Wash all the veggies, slice up the meats, cook whatever items you want to cook, etc. In about two hours, you'll have done enough to have everything ready to eat well for the week (or longer).
Doing the prep work as soon as you return from the market is the ticket. Slice meats into portion sizes, blanch vegetables for freezing, cook those you want ready-to-go, etc. at once. This is the time to cook up a few days worth of quinoa, roast potatoes for freezing, boil pasta to nosh on throughout the week, and get everything set. You'll be shocked at how easy it makes things later. If you like eggs, hard boil a half a dozen and keep in the fridge. With a slice of wheat bread and some olives, it's a great snack, or you can take them on the go.
Freezing fresh doesn't just mean you'll have instant, easy access to ingredients you can then easily cook up, it also helps food to last longer. Plus it's fresher than pre-frozen at the store. Most vegetables should be blanched beforehand -- boil water, drop them in for a few minutes, then transfer to containers or freezer bags. For meat, fish, etc. rinse under cold water before cutting into portions, then freeze separately. You can also cook things like potatoes and other items so that all you need to do when you're hungry is reheat.
A quick, easy way to eat well with a busy schedule is in the extras -- unique mustard, mayonaisse, ketchup, etc., and of course spices. With stores like Whole Foods and Trader Joe's finding cool wasabi mustards, exotic olives and all kinds of gourmet condiments is easy. Or, take traditional store-bought brands and add your own spices, ingredients, etc. There are lots of recipes and ideas to do so via the internet. You'll notice an instant difference in how it can make even the most simple meals taste a little decadent.
