Cheap, easy, and makes a ton! I know this is going to be even better next time, because it was delicious even without the thyme and a mediocre sausage.
Next time, try to find a better sausage (smoked beef sausage from Aldi wasn’t that great) and hope the store hasn’t run out of thyme! Also pump up the heat, it wasn’t nearly spicy enough (even for me). And finally, make sure to add the salt to the beans while you’re soaking them. I forgot and added a ton more later to compensate, but worth trying to do it right next time.
Note that it took around 15 minutes for the pressure cooker to reach pressure, for a total of nearly 30 mins of pressure cooking time.
