Wasn't planning on making soup, it just happened. Had planned on roasting sweet potatoes for tomorrow's lunch but it turned into soup. Into the oven went two sweet potatoes, a red onion, several heads of garlic, a little olive oil, and salt, curry powder, garlic powder, cardamom, cumin, ground corriander, and homemade sambar powder. This I roasted until tender. The whole house smelled wonderful. It was at this point that, instead of packaging up a portion for lunch, I dumped the whole thing in the food processor and ran it with some veggie broth, water, and a splash of store-bought butternut squash soup. A dash more salt and I had roasted sweet potato soup. It's simply delicious and healthful.
The ingredients before my spark of genius (and before I cooked anything).
