When I went grocery shopping for this recipe, our store was out of red peppers so I ended up using 2 orange and 2 yellow. We roasted them over an open flame on the stove (this was a two person job so they didn't totally burn to a crisp), and since I don't have an immersion blender, we just dumped the whole pot into a regular blender, hit pulse a few times, and everything turned out perfect!
Thumbs up on this one. It was a bit time consuming, but well worth it and totally do-able when you're snowed in (like we are now!).
And don't forget about the giveaway - it ends on Monday night!
