1 1/2 cups of liquid (I use 1/2 cup water, 3/4 cup skim milk, and 1/4 cup coconut milk. The recipe I found also recommended using Kefir, but I haven't gone there quite yet. Basically any liquid in any amounts added up to 1 1/2 cups is the best.)
3 oz or more greens (You can do as much or as little as you like. I have been using one nice big organic Kale leaf. The recipe I found recommends using Spinach or Kale, but you can use any green veggies your heart desires. I'm planning to increase my greens but wanted to start off small)
2 Tablespoons orange juice concentrate
1 frozen banana
4 frozen strawberries
Okay here's how I do it - I put the water in first then blend the greens with it until it's smooth. Then I add the other liquids. Doing it this way will help make sure that the greens are well blended in and you're not left with lumps. Then I add the rest of the ingredients. I've been using banana and strawberries because I found a great sale on strawberries and because bananas in any smoothie makes it better, but you can add any kinds of fruit. Some others recommended were blueberries, raspberries, and peaches. If you would like to you can also add honey to sweeten it (I liked it without) and you can add any "boosts" you would like such as ground pumpkin or flax seeds.
