Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with half of the olive oil and a pinch of sea 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 the edges are golden brown.
While the potatoes roast, place the turkey bacon in a cold non-stick skillet and turn the heat to medium, cooking until crisp on both sides.
Remove the bacon from the pan, let it cool slightly, and chop it into bite-sized pieces.
In the same skillet, add the remaining olive oil and sauté the diced red onion until translucent.
Add the fresh spinach to the skillet and cook until just wilted.
Lower the heat to medium-low and pour in the egg whites, stirring gently and constantly until they are fully set and fluffy.
Fold the crispy turkey bacon pieces into the egg white scramble.
Plate the scramble alongside the roasted sweet potatoes and serve immediately.
