Drain and rinse the canned young jackfruit, then use a fork to shred the pieces into a pulled texture.
Press the extra firm tofu to remove excess moisture and crumble it into small, bite-sized pieces.
Heat the olive oil in a large skillet over medium heat and sauté the diced red onion until translucent.
Add the shredded jackfruit, crumbled tofu, and black beans to the skillet, stirring to combine.
Mix in the chipotle peppers, ground cumin, garlic powder, sea salt, and black pepper.
Cook the mixture for 8 to 10 minutes, stirring occasionally, until the jackfruit is tender and the flavors have melded.
While the filling cooks, whisk together the non-fat plain Greek yogurt and lime juice in a small bowl to create the crema.
Warm the corn tortillas in a dry pan or over a low flame until they are soft and slightly charred.
Divide the smoky jackfruit and tofu filling evenly between the warm tortillas.
Top each taco with a generous dollop of the lime crema and a sprinkle of fresh cilantro before serving.
