Preheat the oven to 350°F (175°C) and grease a 9-inch pie dish with olive oil.

In a medium skillet, heat a tablespoon of olive oil, then sauté diced onion and bell pepper for 3-4 minutes until softened.

Add chopped baby spinach to the skillet and cook until wilted, about 2-3 minutes, then add garlic powder, salt, and pepper.

In a large bowl, whisk together eggs, milk, and cottage cheese until combined. Include Italian seasoning, salt, and pepper to taste.

Fold the sautéed vegetable mixture into the egg and cottage cheese blend until evenly incorporated.

Pour the mixture into the greased pie dish and spread evenly.

Bake in the preheated oven for 40-45 minutes until the center is set and the top is golden brown.

Let cool for 5-10 minutes before slicing and serving.
