Step 1

In a large skillet, cook onions in 2 tablespoons oil over medium-low heat until tender and lightly browned, about 10 minutes. Add mushrooms; cook until liquid evaporates and mushrooms are tender, 8-10 minutes.

Step 2

Meanwhile, in a blender, process the next 8 ingredients until smooth. Add jackfruit and sauce to onion mixture; cook, stirring occasionally, until sauce darkens in color and starts to caramelize onto jackfruit, about 15 minutes. Reduce heat to low; stir in pumpkin seeds and nutritional yeast. Cook 10 minutes. Serve jackfruit mixture in tortillas; top as desired.
