Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and halve the cherry tomatoes.
Toss the asparagus and tomatoes on the baking sheet with half of the olive oil, salt, and pepper.
Roast the vegetables for 10-12 minutes until the asparagus is tender-crisp and the tomatoes have slightly blistered.
While the vegetables roast, whisk together the whole eggs, liquid egg whites, and lemon zest in a medium bowl until well combined.
Heat the remaining olive oil in a non-stick skillet over medium-low heat.
Pour the egg mixture into the skillet and let it sit for 30 seconds before gently stirring with a spatula to create soft, creamy curds.
Once the eggs are just set, remove from heat to prevent overcooking.
Arrange the scrambled eggs on a plate alongside the roasted asparagus and tomatoes.
Garnish with crumbled feta cheese and freshly chopped chives before serving.
