Wash and scrub 1 large or 2 medium sweet potatoes to remove any excess dirt. Dry the sweet potatoes with a towel. Feel free to peel the sweet potatoes if desired (optional).
Dice the sweet potatoes into chunks (yields 5 heaping cups diced). Make sure they are relatively the same size to ensure that they cook evenly.
Once the sweet potatoes are completely coated in the oil and spices, place the baking sheet into the oven. Roast the the sweet potatoes for 22-24 minutes, or until they are easily pierced with a fork. Remove the baking sheet from the oven and set aside.
Prepare 1 can of black beans (can use pinto or refried beans if preferred) according to package instructions.
Chop any veggie toppings at this time, such as lettuce or greens of choice, radishes, cabbage, bell peppers, or onions (optional).
For The Avocado Salsa:
Cut 2-3 ripe avocadoes in half. Remove the pit from the avocadoes and discard. Score the avocados with a knife.
Take a spoon and scoop the avocadoes out into a bowl. Scoring them with a knife allows them to scoop them into chunks.
Mince 2 Tbsp. fresh cilantro. Add 2 Tbsp. lime juice, 2 Tbsp. minced cilantro, and ½ tsp. kosher salt to the avocadoes. Gently stir until completely combined.
To Assemble Tacos:
Heat corn tortillas (or flour if not gluten free) in microwave or on the stove top.
Spoon warmed black beans (or beans of choice) onto the tortillas. Add roasted sweet potatoes and top with generous amount of the avocado salsa.
Add any crispy vegetable toppings, such as lettuce or greens of choice, cabbage, or onions. Garnish with pickled jalapenos and hot sauce (optional).
