01 - Set the oven to 425°F to reach full temperature before roasting.
02 - Toss diced potatoes with olive oil, smoked paprika, garlic powder, cumin, chili powder, salt, and black pepper in a large mixing bowl until evenly coated.
03 - Spread the seasoned potatoes in a single layer on a baking sheet and roast for 25 to 30 minutes, tossing halfway through, until golden and crispy on the edges.
04 - Combine black beans, ground cumin, smoked paprika, and salsa in a small saucepan over medium heat. Stir occasionally and cook until heated through, about 5 minutes.
05 - Divide the roasted potatoes among four bowls. Top each portion with a scoop of the warm bean mixture and sprinkle with shredded cheddar cheese 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 a squeeze of fresh lime.
