- 2/3 cup plain Greek yogurt
- 3/4 cup milk
- 12 large eggs

Instructions
- Preheat the Oven – Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with butter or cooking spray.
- Cook the Vegetables – In a skillet over medium heat, warm the butter or olive oil. Add the onions and bell peppers, cooking for 3–4 minutes until softened. Stir in the chopped spinach and cook for 1–2 minutes until wilted. Remove from heat.
- Layer the Potatoes – Arrange the thinly sliced potatoes in an even layer at the bottom of the baking dish. Spread the sautéed vegetables on top.
- Prepare the Egg Mixture – In a large bowl, whisk together the eggs, Greek yogurt, milk, salt, and black pepper until smooth.
- Assemble the Casserole – Pour the egg mixture over the potatoes and vegetables. Sprinkle the shredded cheese evenly on top.
- Bake the Casserole – Cover with aluminum foil and bake for 25 minutes. Remove the foil and continue baking for 15–20 minutes, or until the center is set and the top is golden brown.
- Let it Rest & Serve – Allow the casserole to rest for 5–10 minutes before slicing. Serve warm and enjoy!
