Preheat oven to 400 degrees F (204 C) and place tortillas on a baking sheet. Brush both sides with olive, avocado or refined coconut oil and then sprinkle generously with sea salt, pepper and garlic powder.
If your tortillas are too large, cut them into smaller circles with a pizza cutter and cut the smaller scraps into "chips" to bake alongside the tostada circles.
Bake for 5-10 minutes or until brown and crispy on both sides. Watch them closely as they turn quickly.
In the meantime, cook eggs as desired and set aside.
Remove tostadas from oven and top with eggs and desired toppings.
