I thought this was a great recipe for a "meatless Monday." Our oven was broken so I microwaved the sweet potato for 5 mins and then just cooked them longer on the griddle at the end instead of putting them back in the oven. I was making another recipe that included chipotle peppers, so I threw some of them in as well (about 1 tsp chopped). I wonder if some people who think that this is flavorless are using plain paprika instead of smoked paprika? Two totally different flavor profiles. Between the bit of chipotle that I added and the smoked paprika, these had a really nice, smoky flavor. Will make again.
