Mix mayonnaise and sriracha together in a small bowl. Set aside.
Combine black beans, cumin, chili powder, and oregano. Season with salt to taste. Microwave until hot, about 2-3 minutes.
While beans cook, heat oil in a large frying pan over medium heat. Heat a medium frying pan (dry) on another burner over medium heat.
Lightly beat eggs, then season with salt and pepper. Add to large frying pan, then scramble. Remove pan from heat.
Place one tortilla in medium frying pan. Heat until warm on one side, then flip and heat other side (about one minute total). Repeat with remaining tortillas.
To serve, top tortillas with eggs and beans. Drizzle with the sriracha mayo and sprinkle with feta. Serve immediately. Enjoy!
