Sweet Potato Tacos

0 To make the avocado crema, combine all ingredients listed under avocado crema in the bowl of a food processor and blend until smooth. Taste and add additional salt, if needed. (Note: garlic and jalapeño add additional flavor, but only use them if they are flavors you like. A blender will work here, but you may need to add a splash of water to help bring everything together.) Refrigerate up to a day ahead.
1 Heat a skillet over medium heat.
2 Add cooking oil and then sweet potatoes and saute until they are beginning to turn golden brown, 2 to 3 minutes. Add 2 Tablespoons of water to the pan and cover it with a lid or foil. Steam the sweet potatoes until tender, about 5 minutes.
3 Remove the lid and add black beans and taco seasoning. Saute until seasoning is fragrant and beans are heated through.
4 Cover the tortillas with a slightly damp paper towel and microwave until warm, 15 to 20 seconds.
5 Assemble tacos by filling tortillas with romaine, sweet potato / black bean mixture, crumbled goat cheese and then topping with avocado crema.
