I use www.epicurious.com It has fabulous recipes for the more gourmet cook. Some are harder and some are easier, noted by the clock symbol (for a quick meal). Thye also havea feature called "easy week" with a weeks which ahs a new menu each week of easier recipes. Not all the recipes are "healthy", but they use real ingredients rather than canned soups, etc.
I LOVE to cook, and my husband lost 60 lbs about 5 years ago and heas kept it off by changing his lifestyle rather than dieting. I truly think it is beacsue he cut out fast food and we eat mostly non processed food. We do not diet. I don't always cook low-fat (we occaisonly have pasta with cream sauce, for example), but we eat lots of fresh veggies and very little packaged food.
ALso, Fine Cooking is an excellent magazine with meals that are fairly simple. It is more like a cookbook than a magazine.
Good luck-happy healthy eating!
