I've never tried it - I don't know if black beans cook the same. Most things work though - ive thrown in kidney beans, chickpeas, pretty much anything that I can turn into mush.

I looked it up and it seems it does - https://realfood.tesco.com/recipes/black-bean-burritos.html - basically the exact same recipe and instructions. The kicker is you have to prep black beans beforehand so you can't stumble in from a night out and whip a meal up so easily.
