I've found that the easiest way to "eat clean" is to not rely on cookbooks.
I've spent a bundle on many low carb books, and I have yet to find a recipe that is pallatable to me.
If you concentrate on each individual food type (protein portion, and then a low glycemic carb portion, and a monounsat fat type, if you need to add any oils), you can usually fare better than trying to find "recipes" for the entire meal menu. In other words, pick a LEAN protein source (chicken, turkey, fish, etc) and cook it in a very simple way (grill, broil, bake, etc) using the freshest, organic ingredients you can. Rely on spices to change the proteins up from time to time, so you don't get bored. Then, cook the veggie portion in a very simple way, ie: steamed veggies, grilled, stirfry, etc. Try not to find fussy recipes that incorporate a lot of unneccessary ingredients (sugars, fats, sauces, wine, cream, etc). The less sauces, the better, imho. I've found that most "low carb" or even most "40-30-30" recipe books do not score well in the flavor dept, for me. I've tried The Zone (great nutrition plan, but GROSS flavored recipes, if you ask me. ugh!), South Beach (has a few 40-30-30 recipes that are ok, though not great). I don't do "high protein" type meals, so I can't comment on Atkins. I find that the 40-30-30 type meals are better for me, personally, as opposed to "high protein/no carb". The Zone makes sense. It's about eating everything in moderation, and in the amount based for your specific BMI (body mass index), and activity level.
The easiest type "no brainer" meals for me to prepare are "grilled meats and salads", or "grilled meats and grilled veggies" (as in kabobs, etc), or "broiled fish with broiled veggies, and only a squeeze of lemon and some pepper". Stirfries are super easy, and a fast meal prep. Breakfasts for me are usually an egg white omlette with 1 egg yolk (protein portion), and then some fruit -- a few minutes after I've finished the eggs, or I'll just pack the omlette with some low glycemic veggies. Or, on other days, I'll have a plum or peach (carb portion) with some low fat cheese (protein), and a glass of non sweetened iced tea, or just water, or decaf coffee.
If you think of your meals as "food types" (protein, carb, fat), it will be much easier to prepare your meals, rather than worrying about a "recipe", per se. At least, I find it's easier for me.
When you get "in Season", fresh, organic foods, I find that the food tastes incredible with very little embellishment needed.
And definitely experiment with foods you haven't tried before, esp where salads are concerned. Don't just stick to boring romaine (and iceberg is virtually devoid of any nutrients, btw). There are many "pre made" salad packs at the grocers now, with all sorts of greens, radiccio, etc. Have fun in trying out different foods. I think you will find that eating clean is much easier to prepare than other types of recipes.
