In a skillet over medium heat add the oil and the shaved Brussels sprouts.
Leave them until they are soft, like 3 minutes. Add all the species and mix well. Leave everything for 5 more minutes or until the brussel sprouts begin to brown on the edges.
Be careful not to burn them. When ready, remove from heat and add the vinegar. Mix and set aside.
Tostadas
For putting together the tostadas add 2 tablespoons of refried black beans and spread them well throughout the tostada.
Then add three or four tablespoons of the powerful vegan chorizo, a.k.a. the Brussel sprouts with Mexican spices.
Finish each tostada with slices of avocado and drizzle with cashew or tofu crema.
