Egg White, Tomato, & Avocado Sandwich

Recently a reader reached out asking for a quick way to make her favorite Panera Power Breakfast Sandwich at home.  The Panera version starts with a sprouted bagel flat that is filled with egg whites, cheddar cheese, spinach, tomato, and avocado and clocks in at around 400 calories.  Luckily it couldn't be easier to make this at home.  Since I normally aim to have around a 400 calorie breakfast with fruit and coffee, I knew I wanted to create a version that came in around 250-300 calories.  To do that, I started with a light English muffin (a bagel thin, sprouted bread, or a sandwich thin would also work) and decided on quick microwave egg whites to make this achievable on the busiest mornings.  From there, all you need is tomato, some fresh spinach, avocado, and the cheese.  Easy, filling, and nutritious.
