Cooking Light, both the magazine and the website, is my hands-down, favorite source for recipes. Almost every recipe comes out fantastic (my SO has commented to me that once advantage to my being on this diet is all the great new recipes I've found that he really likes); they give nutritional info for every recipe and it is usually spot-on (not so with a lot of other recipe sources); and most recipes fit in my calorie plan, so I don't get excited by a recipe and then find out a can't eat it when I do the nutritional analysis

.
The food sections in both my local papers (the SF Chroncle and the Fremont Argus) are probably my second favorite. Again, almost every recipe comes out fantastic, they are great about providing accurate nutritional info, and the publish lots of recipes that fit in my calorie plan. They also publish lots that don't fit in my plan (some have had close to 1,000 calories per serving

), but at least the nutritional info is right there so I can see right away that it isn't a recipe for me.
I love cassoreles and I have lots of recipes for low calorie ones. I have a Tamale Pie casserole that comes it at 265 calories per serving; a ground beef, rice, and cheese casserole that comes in at 300 calories per serving; old-fashioned tuna casserole (complete with pasta) that comes in at 360 calories per serving; and an Indian-style ground turkey and rice casserole that comes in at 325 calories per serving. I have lots more. Just like meat loaf (for which I also have lots of low-calorie recipes), casseroles don't have to be high in calories.
