These cheesy waffles are a perfect lunch, brunch or dinner. They have a subtly fiery kick from the jalapenos to compliment the sweetness of the sweet potatoes and are topped with sour cream, rocket/arugula and a crown of cheddar shards for a showstopping crunch. This recipe makes 4-6 waffles (depending on your waffle maker) so serves 3-4 depending on how hungry you are.
