Go Meatless more often-use beans as your replacement for a protein source at least 1 or 2 times a week. They are a fraction of the cost of meat and work well with whole grains, soups and salads.
Snack Smarter-nuts compliment fruit. Together they make up a snack that contains a healthy amount of protein, fat and carbohydrates. Nuts can be bought in bulk which is more economical if you are on a budget.
Shop in Season-Look for fruits and vegetables that are in season. Out of season produce is not only more expensive but it may prove to be less nutritious since it has to be picked earlier to enable it to be transported.
