Rinse the red beans well in a colander.
Put the red beans, the leaves from 1 sprig of oregano, the olive oil, and the feta in a blender and mix. Set aside some feta to finish the hummus if desired.
Add some water or broth if the hummus is not creamy enough.
Finish with the lemon juice.
Season with pepper and sea salt.
Garnish with pieces of feta and sprigs of oregano.
Tips
The feta probably makes the hummus a little drier, so feel free to add a little more water (or broth). Only use the leaves of the oregano. You can also use dried oregano, but the hummus looks more colorful with fresh.
