Preheat your oven to 350°F (175°C). In a large skillet, heat the olive oil over medium heat. Add the chopped red bell pepper, green bell pepper, and onion. Sauté until the veggies are soft, about 6 minutes or so. Stir in the garlic during the last 2 minutes of cooking.
While the vegetables are cooking, chop the sausage and Canadian bacon, if you haven’t already. Once the veggies are tender, remove the skillet from heat and stir in the chopped meats.
In a blender or using an immersion blender, blend the cottage cheese until smooth. Add the eggs and blend until fully combined. Season with salt and pepper to taste.
Pour the egg mixture into a large mixing bowl and stir in the veggie and meat mixture and the shredded cheese until everything is well incorporated.
Lightly grease a 9x13-inch baking dish and pour in the mixture, spreading it out evenly.
Bake for 45 minutes, or until the eggs are fully set. You can test doneness by inserting a toothpick in the center — it should come out clean.
Let the casserole rest for 10–15 minutes before slicing, allowing it to set up. Serve warm and enjoy!
