Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Dice the red bell pepper and chop the broccoli into bite-sized florets.
Toss the vegetables with 0.5 tsp of olive oil and a pinch of salt on the prepared baking sheet, then roast for 12-15 minutes until tender and slightly charred.
While the vegetables roast, slice the chicken sausage into thin rounds and brown them in a non-stick skillet over medium heat for 3-4 minutes.
In a medium bowl, whisk together the whole eggs, egg whites, nutritional yeast, sea salt, and black pepper until the mixture is uniform and frothy.
Add the remaining 0.5 tsp of olive oil to the skillet with the sausage, then pour in the egg mixture.
Using a silicone spatula, gently push the eggs from the edges toward the center, creating soft curds.
When the eggs are nearly set, fold in the roasted vegetables from the oven.
Remove the skillet from the heat while the eggs still look slightly moist to ensure a creamy texture.
Garnish with finely chopped fresh chives and serve immediately.
