Step 1

Make a 1/2 recipe of Nacho Cheese Sauce. Set aside.

Step 2

Measure and add all the dry ingredients to a small bowl (flour, chili powder, garlic powder, cumin and salt). Have the tomato paste and vegetable broth ready and nearby.

Step 3

In a medium pot over medium heat, warm the water. Once warm, pour in the flour/spice mixture and whisk constantly for about a minute. Whisk in the tomato paste, then slowly pour in the broth, whisking constantly.

Step 4

Bring to a boil, then simmer for 5 minutes, whisking often to remove lumps. It should thicken a bit. Remove from heat, and whisk in the vinegar. Taste and add more salt as needed. Set aside.

Step 5

If using whole cauliflower, wash, chop off the florets and place them in a food processor. Pulse, creating rice. Add 2 cups of cauliflower rice to a large pan on the stove.

Step 6

Add the mushrooms and walnuts to the food processor, and pulse until they are a similar consistency as the cauliflower. Don't over process. Add to the pan with the cauliflower.

Step 7

Turn the heat to medium-high, and pour in the vegetable broth (2 tablespoons), spices and soy sauce. Stir to combine. Continue to cook for 10-15 minutes, stirring frequently. Add salt to taste, and remove from heat. Stir in the black beans.

Step 8

Preheat oven to 375 degrees F. Spread 1/2 cup of enchilada sauce in the bottom of a 9x13 inch casserole dish.

Step 9

Wrap 5 tortillas at a time in a damp paper towel, and microwave for 30 seconds to 1 minute to soften. This will make them much easier to roll.

Step 10

Fill each tortilla with a scoop of "meat" and a spoonful of cheese sauce. Roll and place into the prepared pan. Repeat until all the tortillas are used. Pour the rest of the enchilada sauce on top, then pour the rest of the cheese on top of the red sauce.

Step 11

Bake, uncovered, for 20-25 minutes, until bubbly. Top with chopped cilantro and serve hot.
