Preheat your oven to 400°F and dice the potato into 1/2-inch cubes.
Toss the potato cubes on a baking sheet with 0.5 tsp olive oil and a pinch of salt and garlic powder.
Roast the potatoes for 20-25 minutes until they are golden and crispy.
Season the steak with salt, pepper, and garlic powder, then heat the remaining 0.5 tsp olive oil in a cast-iron skillet over medium-high heat.
Sear the steak for 3-4 minutes per side for medium-rare, then let it rest for 5 minutes before slicing into thin strips.
In the same skillet, sauté the diced onions, corn, and black beans for 3-4 minutes until warmed through and slightly charred.
Whisk the Greek yogurt and cottage cheese together in a small bowl until smooth to create a high-protein crema.
Fry the egg in a small non-stick pan to your preferred doneness, keeping the yolk runny if desired.
Assemble the bowl by layering the lettuce, roasted potatoes, bean and corn mixture, and sliced steak, then top with the fried egg and a dollop of the yogurt crema.
