Preheat Oven to 350°F
Grease muffin tins with organic olive oil spray.
In a blender, blend raw spinach, avocado, milk, bananas, egg, vanilla and honey (if using) until smooth. (If using a small blender or food processor, blend the spinach alone first, then add other ingredient and blend again in order to make more room).
In a separate bowl, combine the flour, cinnamon, baking powder, baking soda and salt.
Pour the wet ingredients into the bowl with the dry ingredients and mix with a spatula until combined.
Pour batter into muffin tins, filling approximately 3/4 of the way full.
Bake approximately 18 minutes until muffins feel firm to the touch (before they start to brown).
Let cool enough to handle and remove from tin and place on a wire cooling rack.
Store in an airtight container the refrigerator for up to 4 days or in the freezer for up to 6 months.
