Best way to cook healthy is to eliminate as much as possible, all the processed foods. Things like boxed Mac and cheese, canned soups, etc. , sugary snacks, pre-made roast in the bag stuff, frozen veggies with the sauces already prepared on them, hamburger helpers. Make things simple and fresh. Buy lots of vegetables and fruits and prepare them easily by either grilling them or saute them lightly. Make up you own sauces, you know the salt content and you don't have to worry about what additives have been included. Make up pots of soup and freeze portions of it. Soup is a healthy light meal that is filling and usually pretty inexpensive to make. It may seem more expensive as you get started coking at home, but once you get the cabinets stocked, after that it is much cheaper.
