Preheat your oven to 350°F (175°C).
Crack the 6 large eggs into a bowl, add 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1/2 teaspoon of oregano. Whisk until well combined.
Slice the 3 medium tomatoes and 2 large onions thinly.
Heat 3 tablespoons of olive oil in an oven-safe skillet over medium heat.
Add the sliced onions to the skillet and sauté until they become translucent, about 5 minutes.
Add the sliced tomatoes to the skillet and cook for another 3-4 minutes until they soften.
Pour the egg mixture over the tomatoes and onions in the skillet.
Cook on the stovetop for about 5 minutes, until the edges start to set.
Transfer the skillet to the preheated oven and bake for 10-15 minutes, or until the frittata is fully set and slightly golden on top.
Remove from the oven, let it cool slightly, then slice and serve.
