Looking for input!

I'm going to be changing the way I eat and need help with balanced meals. I am not intrested in any powders or additives, I dont take any vitamins other then vitamin d and folic acid, when I remember(its not uninformed either, my doctor doesnt reccomend vitamins unless you're actually deficient in something). Anyway, I have pretty much no aversion to any food, I will eat mostly all fruits or vegetables, meats, and grains. I am going to be limiting meat intake to once a week, still consuming some dairy and eggs, but mostly the rest will be veggies/fruits/grain/legumes. First, where can you find a concise list of nutrition information on whole foods like beans, nuts, seeds, veggies etc? I do not want to try eating this way and give up because I havent properly balanced my meals. Also, if I made one meal a smoothie, what would be suffiecient nutrition? Thus far I have made smoothies with the following ingredents: Usually 1 banana, 1/2 cup to 1 cup of frozen fruit like blueberries(or mangos/cherries/strawberries), handful of nuts(walnuts/pecans), and either mixed with coconut milk(the carton variety unflavoured), or with 1/2 cup greek yogurt topped off with a bit of water for blending. It keeps me full but I guess im just wondeing if its sufficient for a meal if I started the 5 meal a day approach? Im not extreme in regards to eating the exact same meals everyday, I want variety but dont know where to start. Any good cook books or blogs? Also, what kind of protein should be consumed in a day? I do not want to over do it! Thanks for any tips or advice, its appreciated! Oh I have to mention I am currently breastfeeding a 2.5 month old so Im not adverse to a bit of extra healthy fats, I dont want to be lacking in the calorie department.
