Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the potato into half-inch cubes and slice the carrot into rounds.
Toss the potato and carrot with olive oil, sea salt, black pepper, and garlic powder on the baking sheet.
Roast the vegetables for 20-25 minutes, tossing halfway through, until they are golden brown and tender.
While the vegetables roast, bring a small pot of water to a boil and carefully lower in the whole eggs to cook for 6.5 minutes.
Immediately transfer the cooked eggs to an ice bath to stop the cooking process, then peel and set aside.
In a non-stick skillet over medium heat, cook the liquid egg whites, stirring constantly until they are scrambled and fully set.
Warm the cooked lentils in a separate pan and fold in the scrambled egg whites until well combined.
Portion the lentil and egg white mixture into bowls, top with the roasted vegetables, and finish with the halved soft-boiled eggs.
