Beat the eggs together in a small bowl. Heat a skillet over medium, spray with cooking spray (or oil) and add the eggs.
Cook the eggs (scramble them!) until they're almost fully cooked, then add the beans, salsa, spinach and a pinch of salt and pepper. Continue cooking until the spinach has wilted.
Heat the tortillas in the microwave for 30 seconds. Transfer to a plate and fill each taco with the egg mixture.
Top with cilantro, avocado and hot sauce if desired. Enjoy!
