Preheat your oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper.

In a large bowl, combine rolled oats, chopped almonds, and sunflower seeds. Add honey, melted coconut oil, vanilla extract, and salt; mix until sticky.

Transfer the mixture into the prepared baking pan and press down firmly and evenly.

Bake for 15-20 minutes until golden brown and firm. Allow to cool in the pan.

In a saucepan, cook mixed berries, chia seeds, and maple syrup over medium heat for 5-7 minutes until thickened.

Spread the warm berry mixture evenly over the cooled base.

Cool completely in the pan on a wire rack, then lift out and cut into bars.

Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
