Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the diced yellow potato and sliced zucchini with olive oil, sea salt, and black pepper until evenly coated.
Spread the vegetables in a single layer on the baking sheet and roast for 18 minutes until they are golden and tender.
While the vegetables roast, heat a non-stick skillet over medium heat and add the mixed vegetables to warm through for 3 minutes.
Drain the canned Miruna and flake it into the skillet, stirring to combine with the mixed vegetables.
In a small bowl, whisk the eggs with garlic powder, then pour the mixture into the skillet with the Miruna.
Gently scramble the eggs and Miruna over medium-low heat until the eggs are set and fluffy.
Transfer the roasted potatoes and zucchini to a plate, top with the egg scramble, and finish with a dollop of sour cream.
