Scramble the eggs in a skillet over medium heat until fluffy and fully cooked.
Lay the tortillas flat and spread a thin layer of mayo ketchup or your preferred sauce over one side of each tortilla.
Add several pieces of potatoes on top of the sauce.
Layer scrambled eggs, diced onion, jalapeños, and shredded cheddar cheese over the potatoes.
Place avocado slices in the center and top with a little extra cheese to help seal the tacos.
