Sweet potato and black bean sauce

So, I've known for a while that sweet potatoes and black beans are a thing in the veg*n community, but I just never found a recipe that grabbed me.

Well, today, I'm down to bare bones pantry supplies plus a pureed chili-spiced black bean soup I whipped up the other day.  I decided to spoon it over some steamed sweet potato chunks ,and it turned out great!  I started out with my own Dimo's Mexican spice mix plus some black beans and onion and that's it:

2 cups of dried black beans
1 medium onion, chopped
1 Tbs of Dimo's Mexican spice mix.

Soak the beans overnight, drain, rinse, and put in a pot with enough water to cover to your second knuckle.  In another pan, dry saute the onion (add a splash of water when things start to stick) until translucent.  Add the spice mix and the garlic and saute till the onion is coated with the spices.  Toss into the pot with the beans, and bring to a boil, reduce heat and simmer for an hour or so or until the beans are very soft.   Puree with a stick blender, or else in a stand blender in batches.

Peel and cut a 1 lb sweet potato into medium sized chunks and put in a steamer basket and steam till tender.  Transfer to a bowl, or soup plate, and pour the soup over the sweet potato chunks and chow down!
