Superfood Blueberry Muffins
The recipe could be easily modified to reduce the fat content (add more applesauce and use less oil) and you could use less sugar if you don't have a sweet tooth.
Either plain or flavored Greek yogurt can be used.
If you taste the batter before you bake, don't be worried about the yogurt taste. Once baked, there is little to no trace of the yogurt. Plain or flavored yogurt will work fine in this recipe.
