My first breakfast every day, and my post workout repleishment, is my nutrient dense milkshake tasting smoothie. It has evolved to still have a very good fruity taste, but I found that is a very good way to get in a good dose of vegetables.
With the fruits that I use, it still taste like a fruity milkshake, and I must admit I have trouble starting the day without it, especially if I'm traveling or otherwise not at home. I would suggest if starting with smoothies, to start with an all fruit smoothie (with a good protein powder), and progressively add vegetables, so the taste will always be pleasing. Take your time and experiment to get the taste that your taste buds and body will start to love.
I learned how to totally hide the taste of my vegetables, see last note at bottom of recipe.
This same smoothie works for my post-workout smoothie. The Blueberries or Blackberries are extremely healthy, but more important for me they make the smoothie a nice purple color. Green, muddy colored smoothies are not visually appealing to me.
Doug's Every Morning "Power Smoothie"
(Most days I get almost all these things in the smoothie but obviously I may leave out an item or two or three or four here and there)
Half handful of Frozen Organic Strawberries
1 tbsp of Goji Berries
Handful of Organic Frozen Black Raspberries or Blueberries (gives smoothie a purple berry color as opposed to green color)
1/2 Handful of diced frozen Organic Bananas (to give it that "milk shake" texture)
Organic Turmeric and Ginger (as much of each as taste allows)
1/4 cup Trader Joe's organic shredded broccoli stems
Green Tea (and/or water) as my liquid base, I only need a half glass of liquid
A little bit of Soliga Honey
one organic apple core , when available, saved from an apple I ate, if I have one fresh or previously frozen (read why)
1 serving Garden of Life plant based protein
1/2 tsp powdered Reishi Mushroom
1/2 tsp Source Naturals Yaeyama Chlorella
1/2 tbsp red maca
1 tbsp raw Cacao Chocolate Nibs
(I go off and on with Genesis Today Total Goji 100, Sea Buckthorn, Acai and Mangosteen, for a couple of months at a time, because they are so expensive, over $30 per bottle each. But they are incredible!!!!!)
(I also use Vega Performance Protein, berry flavor, an awesome product, it gives smoothie more fruity flavor if you want to totally mask the taste of veggies. I will mix my two protein powders sometimes, to get the right sweetness)
