Cooking Instructions:
Preheat your oven to 350°F (175°C) and grease a baking dish with olive oil or ghee.
In a large mixing bowl, whisk together the eggs, salt, and pepper until well combined.
Add the cooked lentils, chopped spinach, diced onions, and bell peppers to the egg mixture. Stir until all ingredients are evenly distributed.
Pour the egg and vegetable mixture into the prepared baking dish. If desired, sprinkle shredded cheese on top.
Bake in the preheated oven for 25-30 minutes or until the eggs are set and the top is lightly golden.
Allow the casserole to cool for a few minutes before slicing and serving.
For best results, you can prepare this breakfast casserole the night before and let it chill in the refrigerator. Simply reheat individual portions in the microwave in the morning for a quick, nutritious breakfast.
You can also experiment with different spices and herbs to enhance the flavor profile of the dish, making it a delightful addition to your slow-carb meal plan.
