In a blender, combine the flour, skim milk, egg whites, vanilla extract, and sea salt until completely smooth.
Let the batter rest for 10 minutes at room temperature to allow the flour to fully hydrate for a better texture.
In a small saucepan over medium heat, combine the mixed berries, maple syrup, and lemon juice.
Simmer the berry mixture for 5-7 minutes, stirring occasionally, until the berries burst and the sauce becomes glossy.
Lightly coat a non-stick skillet with coconut oil and place over medium-low heat.
Pour approximately 3 tablespoons of batter into the center of the pan, tilting and swirling it immediately to create a thin, even circle.
Cook for 60-90 seconds until the edges are dry and slightly golden, then flip and cook for an additional 30 seconds.
Place the crêpes on a plate, fill each with a dollop of Greek yogurt, fold them over, and finish with the warm berry compote.
