An egg white frittata is a great low-sodium, low-calorie, and low-carb breakfast or brunch option. Load this frittata up with your favorite vegetables and cook it overnight in the slow cooker to wake up to an easy & healthy vegetarian breakfast.
Another cookbook recipe! This one is from my latest cookbook, The Low Sodium Slow Cooker Cookbook.
What Vegetables To Use
As with most fritattas, you can get creative with this recipe. It actually works best when you use your favorite vegetables. I used a combination of chopped fresh spinach and sliced roma tomatoes. Other suggestions include mushrooms, bell peppers, onion, etc. You can also get creative with the cheese. The original recipe in the cookbook uses shredded cheddar cheese but I substituted shredded mozzarella. I think the mozzarella went better with the spinach and tomatoes than cheddar would have. So the point is, if you have a winning veggie/cheese combo then use it.
What Type Of Milk To Use
Use the milk of your choice, I of course used almond milk. To make this vegan, use almond milk and omit the cheese. This is a great meal prep recipe! One batch of this will serve you breakfast all week.
