Sweet Potato Tater Tot Nachos ("Totchos")

Preheat oven to 425 degrees F. Spread sweet potato tots in a single layer in a large cast-iron skillet. Bake, stirring once, until crisp, about 30 minutes.

Meanwhile, combine tomato, jalapeño, lime juice, cilantro and salt in a medium bowl. Combine sour cream, water and chili powder in a small bowl. Set both mixtures aside.

Push the tots to the center of the pan. Top with beans and cheese and return to the oven. Bake until the cheese is melted, 2 to 3 minutes more. Using a slotted spoon, spread the reserved tomato mixture over the top. Top with avocado and lettuce. Drizzle the reserved sour cream mixture over the top and garnish with cilantro, if desired.
