I would also like to add that an inexpensive blender may not do a good job with the raw carrot.
Default Green Smoothie
1 C plain greek yogurt
1/2 C cold water
about 3 C somewhat packed down spinach or torn up kale
3/4 C baby carrots
1 1/2 to 2 C fresh or frozen fruit, like strawberries, blueberries, mango chunks, pineapple chunks, peach chunks, apple slices, or peeled oranges
optional: 2 or so Tbsp lemon or lime juice
Place everything in the blender in the order listed in the recipe. Put on lid and blend according to your blender's directions until smooth.
Yield: 2 large smoothies or 4 small ones
