Preheat the oven to 175C/350F
Line a muffin tray with 6 muffin cases and lightly grease each one.
Put all the wet ingredients (including the mashed avocado and vegetables) into a small bowl and whisk together lightly by hand. If the avocado is not ripe then it will be chunky and won't make for nice muffins.
In another bowl, put all the dry ingredients and whisk together lightly by hand.
Pour the wet ingredients into the dry ingredients bowl and stir until combined.Do not over mix as the muffins will turn out tough.
Divide the mixture evenly into the greased cases.
Bake for 30 to 35 minutes or until cooked through.
Allow the muffins to cool in the tin before removing. Store in an airtight container.
