Heat the olive oil in a large non-stick skillet over medium heat.
Add the turkey bacon slices and cook for 3-4 minutes per side until they reach a crispy texture.
Remove the bacon from the pan, let it cool slightly, and chop it into small bite-sized pieces.
Add the diced yellow onions and sliced mushrooms to the same skillet, sautéing for 5-6 minutes until the mushrooms are golden and the onions are soft.
In a medium bowl, whisk together the whole eggs, liquid egg whites, sea salt, and black pepper until well combined.
Stir the chopped bacon and diced tomatoes into the skillet with the sautéed vegetables.
Pour the egg mixture into the skillet and reduce the heat to medium-low.
Use a spatula to gently push the eggs from the edges toward the center, cooking until the scramble is just set and still moist.
Remove from heat, sprinkle with fresh chives, and serve immediately.
