For the strawberry sauce:
Stir together berries, sugar and lemon juice in a small saucepan over medium heat. Bring to a simmer, stirring and crushing berries with the back of a wooden spoon. Simmer for 5 to 7 minutes, or until sugar has dissolved and berries begin to break down. Remove from heat and stir in vanilla extract. Transfer to a blender and pulse until smooth.
For the waffles:
In a saucepan or in a double boiler, stir butter and chocolate until melted and smooth. Remove from heat and stir in sugar. Whisk in eggs and vanilla, followed by milk. Add in the flour, cocoa powder, baking powder and salt until just combined.
