Preheat the oven to 400 degrees and line a large baking tray with parchment paper.
Prep your sweet potato and zucchini.
In a small mixing bowl, mix together the spices (cumin, paprika, chili powder, oregano, salt).
Add the vegetables to the baking tray and coat well with olive oil and spices.
Cook for 20 minutes, or until the vegetables are soft (flip the vegetables over and shake at the 10 minute mark).
While the vegetables cook, rinse and drain black beans. Place all ingredients for your avocado sauce into a high speed blender and blend until smooth.
Remove vegetables from oven and let cool, then stuff each tortilla with roasted vegetables and black beans (about 1/4 cup each) and then top with the avocado sauce and cilantro + ENJOY!
