Lightly grease a small oven-safe pan or baking dish and press the 1 tortilla into it to form a crust.
Crack the 4 eggs directly into the tortilla shell, add the ½ cup cottage cheese, and gently stir with a fork until just combined.
Add the ½ cup diced tomatoes, 3 tablespoons feta, 2 tablespoons basil, salt, and pepper, stirring lightly to distribute the filling without tearing the tortilla.
Bake for 12 to 15 minutes, until the eggs are just set in the center.
Let it cool slightly, then slice and serve warm.
Notes
A light brush or spray of oil under the tortilla helps keep the bottom crisp and prevents sticking.
For extra crisp edges, brush the exposed tortilla with olive oil before baking.
This holds together well once cooled and is just as good at room temperature.
