To quickly cook your sweetpotatoes, poke them with a few holes with a fork, and place on a microwave safe plate. Microwave the four potatoes together for 6 to 9 minutes, depending on size, until tender. As an alternative, you can bake the sweetpotatoes (after poking with a fork) in the oven at 425°F for 40-50 minutes, until tender. Set aside when done.
Meanwhile, in a medium mixing bowl, mix together the light mayo, Greek yogurt, and lime juice until well combined. Add the green onions, cilantro, and parmesan, and set aside for now.
Heat a large skillet over medium heat. Add the butter and let it melt. Add the corn and cook for 2 minutes.
Add the jalapeno to the skillet with the corn, give everything a good stir, and continue to cook for another 2 minutes.
Add the garlic, chili powder, smoked paprika, and salt to the skillet. Stir and continue cooking for another 1-2 minutes, until the corn starts to lightly brown on some of the sides.
Remove from heat. Add the skillet ingredients to the bowl with the mayo/yogurt mixture. Stir everything until well combined.
Slice the cooked sweetpotatoes open and stuff with the corn filling. Enjoy!
