Preheat the oven to 400°F (200°C). Line a baking sheet with a sheet of parchment paper.
Place the corn tortilla on a baking sheet and spread the pizza sauce evenly over the top of the pizza. Keep the sauce within .25 inch of the edge of the tortilla.
Sprinkle the mozzarella cheese over the sauce. Build it up a little denser toward the edges of the tortilla to contain the egg. Spread your cooked meat on top of the cheese.
Crack an egg in the center of the tortilla, keeping the yolk intact. Season with salt and pepper.
Bake for 8-10 minutes for a runny yolk or 10-12 minutes for a firmer yolk. Remove from the oven and serve warm.
