Preheat your oven to 375°F (190°C). Grease an oven-safe skillet (10-inch works well) lightly with a small amount of oil or cooking spray.
In a large bowl, combine the rolled oats, baking powder, cinnamon, salt, flaxseed and almonds. Mix well.
In a separate bowl, whisk together the soy milk, eggs, maple syrup, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined. Gently fold in the wild blueberries, reserving a few for topping.
Pour the oatmeal mixture into the prepared skillet, spreading it evenly.
Place the skillet in the preheated oven and bake for 30-35 minutes, or until the oatmeal is set and the edges are golden.
Let the skillet bake cool slightly before serving. Slice into wedges or scoop out portions. Serve as is or with a dollop of yogurt, a drizzle of maple syrup, almonds or fresh fruit on top.
