Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with olive oil and a pinch of salt, then spread them in a single layer on the baking sheet.
Roast the sweet potatoes for 20-25 minutes until they are tender and slightly browned.
While the potatoes roast, cook the turkey bacon in a non-stick skillet over medium heat until it reaches your desired crispness.
Remove the bacon, chop it into bite-sized pieces, and set it aside.
In the same skillet, add the fresh spinach and sauté for 1-2 minutes until wilted.
Whisk the egg whites and the whole egg together in a bowl, then pour them into the skillet with the spinach.
Gently scramble the eggs over medium-low heat until just set, then fold in the crispy turkey bacon pieces.
Plate the egg scramble alongside the roasted sweet potatoes and top with fresh avocado slices.
