Preheat your oven to 325°F.
If you choose to cook your veggies, get those going.
Place a pan over medium-high heat.
When the pan is hot, add the olive oil and vegetables
While the vegetables cook, continue to the next step.
Combine the eggs, egg whites, yogurt, cheese, seasonings, and parsley in a bowl.
Whisk the egg mixture until thoroughly combined, trying not to incorporate too much air.
When the peppers are done, remove them from the heat to start cooling.
Spray a small, high-sided baking sheet with nonstick cooking spray.
Distribute the peppers and scallions in the bottom of the baking dish.
Next, top the peppers and onions with the sun-dried tomatoes.
Pour the egg mixture over the peppers and sun-dried tomatoes.
Place the pan in the oven and bake for 20 minutes.
The center should be firm but not hard. If it is still soft, continue cooking and check for doneness every five minutes.
Remove from the oven and cool in the pan for 10 minutes.
To serve, sprinkle with the tops of the scallions and a little extra Parmesan cheese.
