In a large skillet, sauté the onion over medium heat until it becomes translucent, about 3-4 minutes.
Add the minced garlic, cooking for an additional minute until fragrant.
Stir in the ground turkey, breaking it apart with a spatula, and cook until browned, about 7-10 minutes.
Mix in the black beans, chili powder, cumin, smoked paprika, salt, and black pepper. Combine everything and cook for another 2-3 minutes, allowing the flavors to meld together.
In a lightly greased baking dish, lay the corn tortillas flat and spoon the turkey and black bean mixture into each tortilla.
Top each filled tortilla with shredded cheese.
Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes.
Remove the foil and bake for another 5 minutes, or until the cheese is bubbling and slightly golden.
Remove from the oven and let it cool for a couple of minutes before serving.
Serve the tacos topped with diced tomatoes, avocado, fresh cilantro, and a dollop of sour cream or Greek yogurt.
