Heat oil on an over medium heat. When the oil is hot, add the corn tortillas and fry just until crisp, about 2 minutes. Remove and set aside.
In the same frying pan, add the onion and jalapeño. Cook on medium-high heat. Add tomato and season with salt and pepper.
While the veggies are cooking, add the eggs to a bowl, season with salt, and pepper, add water. Whisk with a fork until smooth.
Add crispy tortillas back in the pan and the egg mixture, and let sit for about 30 seconds or until it starts to set on the bottom.
Gently stir to mix the eggs with the tortillas and veggies. Cook eggs until set or they reach your desired consistency.
Serve immediately, add salsa, hot sauce and any other desired toppings.
