Preheat your oven to 350°F (175°C).
In a large mixing bowl, whisk together the eggs and milk until well combined. Season with salt and pepper.
Stir in the crumbled feta cheese.
Heat a non-stick, oven-safe skillet over medium heat. Sauté the diced red onion until translucent, about 2-3 minutes.
Add the spinach to the skillet and cook until just wilted, approximately 1-2 minutes.
Pour the egg mixture over the sautéed onions and spinach. Sprinkle the diced tomatoes, sliced Kalamata olives, and oregano evenly over the top.
Cook on the stovetop until the edges begin to set, about 2-4 minutes.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the frittata is set and lightly golden on top.
Remove from the oven, let it cool for a few minutes, then slice and serve.
