In a large bowl, combine the flour, rolled oats, and ground chia seeds.
Sift in the baking powder, then add the salt. Stir to combine.
Add the lemon zest, juice, and milk and whisk until combined.
Add the berries and gently stir to incorporate.
Lightly oil a non-stick skillet (simply wipe oil onto the pan using a paper towel: if you have a very good non-stick pan you won’t need much). Heat the pan over medium-high heat for a few minutes, until hot. Reduce the heat to medium or medium-low and let rest for a minute.
Using a ladle, scoop ¼- to ⅓-cup portions of the batter into the skillet.
Cook the pancakes for several minutes, until small bubbles form on the outer edges and in the centres, and the pancakes start to look dry on the top. Wait until those bubbles form, or the pancakes might be tricky to flip. Once ready, flip the pancakes and lightly cook on the other side, about a minute.
Repeat until all the batter is used.
Milk note: As you use up the batter, you’ll notice that it becomes much thicker. Add an extra tablespoon of milk as needed to thin the mixture as you work through batches.
