Preheat oven to 356F (180C).
In a blender, add the flours, eggs, milk, salt, baking powder and blend until smooth.
Grease a muffin tray (I like spreading some butter using a piece of paper towel).
Pour the mixture into 12 muffins. Make sure just to add a small amount of batter so that the muffins will be thinner and look more like a pizza.
Sprinkle chia seeds on top, followed by the mozzarella cheese, cherry tomatoes, and oregano.
Bake for 15 minutes, let them cool a bit and remove from baking tray.
