Creating breakfast tacos with feta, arugula, and avocado is simple when you follow these steps:

1. Heat the Tortillas: In a dry skillet over medium heat, warm each tortilla for about 30 seconds on each side until soft and pliable.
2. Whisk Eggs: In a bowl, whisk together the eggs, adding salt, pepper, and paprika (if using).
3. Cook the Eggs: Heat olive oil in the same skillet over medium-low heat. Pour in the whisked eggs and cook gently, stirring frequently, until they are just set (about 5 minutes).
4. Assemble the Tacos: On each warm tortilla, place a generous scoop of scrambled eggs.
5. Add Toppings: Top with sliced avocado, crumbled feta cheese, and a handful of arugula.
6. Adjust Seasoning: Sprinkle with additional salt and pepper to taste, if desired.
7. Serve: Serve immediately with lime wedges on the side for added zest.
