Cook's Illustrated is the bible of deliciousness, but they've been doing a "light and healthy" collection that's pretty darn good. I've weaned my wife off of Betty Crocker brownies and onto their 1/3 calories brownies. The recipes aren't up to T standards, they aren't low-carb or anything, they just have 1/3 of the calories and are still good enough to serve to company.
The panzanelle is right now a favorite. It's basically just grilled vegetables (zukes, red peppers, red onions), grilled bread, some chopped basil, 3 tbsp EVOO, 1 tbsp balsamic, 2 tbsp goat cheese, pepper, salt, toss.
Like I said, not low carb, but low calorie.
Some other stuff CI has is how to flawlessly grill salmon. Grilled wild salmon is like eating fish butter. Mmm. Get a filet, SKIN ON (that's important). Marinate in some soy, a little honey, a little sesame oil, some hot pepper. Crank up the grill, get the grate as close to the fire as you can. When you're ready to grill, wipe down the grates with some paper towels soaked in veggie oil. There will be some flame. Don't be a pussy. Put the filets down skin side down. Cook for three minutes or until dark char marks form. While that's happening, spray the topsides down with nonstick cooking spray. Using tongs and a spatula, slip the salmon hunks onto the flesh side, cook another two minutes. Take them off and eat them!
I might have added that last bit. I love salmon. I love honey too. I was bit by a bear once.
