Preheat oven to 375 degrees F. Spray muffin pan with nonstick cooking spray and set aside.
In a medium bowl whisk the egg and sugar for a minute or two. Add the yogurt, oil, honey, vanilla, cinnamon, lemon juice and lemon zest and whisk until fully combined.
In a separate large mixing bowl, whisk together the flour, baking powder, baking soda and salt.
Pour the wet ingredients into the dry ingredients and mix until most of the flour has been incorporated. If you see a little that isn't yet mixed, that's ok. Do not overmix or you will have very dense, not so fluffy muffins. The batter will be thick.
With a rubber spatula, gently fold in the chia seeds and berries.
Carefully spoon batter into muffin pan and bake for approximately 15 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.
