Preheat your oven to 350°F (175°C). In a medium skillet, heat 1 tablespoon of olive oil over medium heat. Add diced onion and bell pepper, sautéing for 3-4 minutes until they soften and become fragrant. Stir in fresh baby spinach, seasoning with garlic powder, salt, and pepper; cook until the spinach wilts, about 2-3 minutes.

In a large mixing bowl, combine 6 eggs, 1 cup of milk, and 1 cup of cottage cheese, whisking until smooth. Incorporate the sautéed vegetable mixture from the skillet and fold in 1 cup of shredded cheddar cheese gently. Season the mixture with Italian seasoning, salt, and pepper to taste.

Lightly grease a 9-inch pie dish or quiche pan with a small amount of olive oil or non-stick cooking spray. Carefully pour the filling mixture into the prepared dish, smoothing the top with a spatula.

Place the quiche in the preheated oven and bake for 40-45 minutes, until the top is golden brown and a knife inserted in the center comes out clean.

Once baked, remove the quiche from the oven and let it cool for about 10 minutes. Cut into wedges and serve warm or at room temperature.
