This was amazingly good. I had a couple of edits. 1) I added salt to the vegetables before roasting them. 2) While blending, I added heavy cream to help with blending. 3) My pot was very full, so I opted for leaving the kale out. 4) I used 3 sweet potatoes and only 1 pepper.
If you like heat, I would suggest 2 of your preferred hot pepers to use while roasting.
My husband and I loved it, the kids took convincing to eat it, but they did.
