01 - Set the oven to 425°F to ensure proper roasting temperature.
02 - Toss diced potatoes with olive oil, smoked paprika, garlic powder, ground cumin, chili powder, salt, and black pepper in a large mixing bowl. Spread evenly across a baking sheet in a single layer.
03 - Roast for 25 to 30 minutes, tossing halfway through, until golden brown and crispy on the edges.
04 - While the potatoes roast, combine black beans, ground cumin, smoked paprika, and salsa in a small saucepan. Heat over medium, stirring occasionally, until warmed through, about 5 minutes.
05 - Divide the roasted potatoes among four serving bowls. Top each portion with a scoop of the warm bean mixture, then sprinkle shredded cheddar cheese over the top so it begins to melt.
06 - Arrange cherry tomatoes, red onion, corn kernels, diced avocado, chopped cilantro, and sliced jalapeños over each bowl as desired.
07 - Drizzle sour cream or Greek yogurt over the bowls and serve immediately with lime wedges on the side.
