Prepare the bagels as instructed and let them cool.
Heat a large nonstick skillet over medium heat, spray with oil.
Scramble the eggs with salt and pepper until they just set. Set aside.
Prepare the sandwiches. Cut the bagels in half, and make the sandwiches by layering the eggs, bacon, tomato, avocado and red pepper flakes, if using.
Eat right away.
