Heat a nonstick skillet on medium heat, and toast your tortillas. As you take them off the heat, fold them into "taco" shape and place a slice of cheese inside. I like to double up my tortillas so you'd use 2 tortillas for each taco.
After all tortillas are toasted, let pan cool slightly then add the olive oil. Add in the shrimp, season with garlic powder, salt, and pepper, and saute for 5-6 minutes, until completely pink and slightly charred. Remove shrimp from pan and set aside.
Add a little more olive oil to the pan, if needed, and make your scrambled eggs.
Divide eggs evenly between your prepared tortillas, then top each taco with a couple of shrimp, tomatoes, and avocado.
Serve immediately!
