Preheat oven to 400° F.

In a small bowl mix together chili powder, paprika, cumin, salt, oregano, garlic powder, onion powder, and cayenne pepper (if using).

Toss sweet potato pieces with vegetable oil and half the seasoning mixture, about 2 tablespoons. Bake for 15-20 minutes until tender and cooked through.

Meanwhile, cook beef over medium-high heat for about 5-7 minutes until cooked through. Drain any large quantities of fat, leaving about 1 tablespoon. Add beans, fresh corn, and remaining seasoning mixture. Toss to fully coat and heat through.

To serve, place all ingredients in separate dishes for family style serving, or make individual bowls.

Serve with any desired optional garnishes (sour cream, jalapeños, sliced green onion, chopped cilantro, lime slices, crumbled feta, etc.).
