Heat the olive oil in a large skillet over medium heat. Add the ground turkey and break it up with a spoon. Cook until no pink remains, about 6 minutes.
Stir in the chili powder, cumin, salt, and black pepper. Add the black beans and cook for 2 more minutes until everything is warmed through. Remove the pan from heat.
In a mixing bowl, combine the pumpkin puree, diced tomatoes, red onion, garlic, cilantro, and lime juice. Stir until the salsa is evenly mixed.
Warm the corn tortillas in a dry skillet or microwave for 20 seconds. Spoon the turkey and bean mixture into each tortilla. Top with a generous scoop of pumpkin salsa.
