Finely chop the potatoes and toss with 2-3 teaspoons of oil and 1/2 teaspoon each of salt and pepper, tossing well to coat. Place on a baking sheet and roast for 30 minutes until crispy.
Make the scramble
Heat the remaining tablespoon of oil in a skillet, then add the onion and pepper. Cook, stirring often, until onion is cooked through, about 8 minutes. Crumble the tofu between your hands into the skillet, it should look "scrambled" Add the remaining 1/4 teaspoon salt, turmeric and paprika. Stir to combine and continue to cook over medium heat until warm, about 5 minutes.
Add the black beans and stir to combine. Taste, adjusting seasoning as needed.
Assemble
Start with a warmed tortilla (heat it in a dry skillet for 1-2 minutes per side). Layer the tofu scramble, black beans and the roasted sweet potatoes. Top with the avocado salsa verde.
Notes
*To speed the process up for a quick weekday meal, warm the sweet potatoes by either steaming them or pop them in the microwave for a few minutes. I cubed and then steam mine until soft, about 1-2 minutes. Then, you can roast in the oven (toss with oil and salt/pepper as above and roast for ~10 minutes until cooked through and slightly crispy on the outside.) You could also do this on the stove.** For a quick avocado salsa verde, blend 1 cup of your favorite salsa verde with 1 avocado. You can also just use sliced avocados if you don't want the salsa.
