Smoothies are a great idea for a healthy meal or snack and a nice way to get some more fruits and veggies into your diet. When making a smoothie to replace a meal or snack, be sure to turn it into a complete meal by adding fruits and/or veggies, extra fiber and protein.
Use fresh or frozen berries or fruit and add some veggies in where you can. Grated carrots work nicely, and so does spinach. For protein, try 1/4 cup of hemp hearts or a good quality protein powder. For fiber, try adding a couple of tablespoons of ground flax seed.
