Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, toss the diced potatoes with olive oil, smoked paprika, cumin, garlic powder, salt, and pepper until evenly coated.
Spread the potatoes out on the prepared baking sheet in a single layer. Bake for 25-30 minutes, tossing halfway through, until the potatoes are golden and crispy.
While the potatoes are baking, prepare the toppings. In a small bowl, mix the black beans, corn, and diced tomatoes together. Season with salt and pepper to taste.
Once the potatoes are done, remove them from the oven and let them cool slightly.
In serving bowls, layer the crispy potatoes as the base, then spoon over the black bean, corn, and tomato mixture.
Top each bowl with diced avocado, shredded cheddar cheese, and a dollop of sour cream.
Garnish with fresh cilantro and serve with lime wedges on the side for an extra zing.
Notes
Feel free to customize toppings based on your preference.
