Olive Oil for Butter
Your family may not get festive with Paula Deen's infamous Fried Butter Balls, but there's no way butter's golden goodness doesn't make it into your meal, unless you all went vegan. Rolls with herb butter, mashed potatoes drowning in the stuff -- and that's not counting butter cookies, butter tarts and all the other goodies baked with it. Butter is delicious, but it's high in cholesterol and especially saturated fats.
A simple switch: olive oil, which has good fats and no cholesterol. Some great extra-virgin goes perfectly with bread, while light olive oil works well in baking (although you'll need to check a cookbook for the correct proportions when you substitute).
