These are amazing!
I use left over paste & salsa in a wrap or sandwich the next day
First make the black bean paste.
Place all the paste ingredients in a blender and pulse into a rough paste
To make the salsa soak the red onion in the vinegar for a few minutes then add all the other ingredients and stir well
Take one of the tortillas and spread 2 tbsp bean paste creating a large circle
Add sour cream, salsa, jalapeños & cheese
Top with another tortilla and fry in a dry pan on both sides until browned
Cut into triangles and serve with remaining salsa and coriander
