|Cauliflower and Mushroom mix|
|Mix with added chicken and sauce/season|
- In a large, high-sided skillet, heat oil on medium-high. Add onion and sauté for 5 minutes, until begins to soften. Stir in garlic and sauté for 30 more seconds.
- Add mushrooms and cauliflower and stir constantly for 2 minutes, until vegetables start to release water and shrink. Continue to cook, stirring occasionally until mushrooms are about half their original size and cauliflower is fork tender, about 15 minutes.
- In a small mixing bowl, whisk together tomato paste, 1/4 cup water, chile powder, cumin, salt and pepper. Add to mushroom mixture along with corn. Stir to combine, then cover. Reduce heat to medium-low and simmer for 15 minutes.
- Warm tortillas over the flame of a gas stove or in a warm oven. To assemble tacos, fill each tortilla with 1/4 cup mushroom filling. Top with lettuce, avocado, cheese and sour cream, divided evenly.
