Preheat the oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the cubed potatoes with 1 tablespoon of olive oil, dried oregano, and a pinch of salt and pepper.
Spread the potatoes in a single layer on the baking sheet and roast for 20-25 minutes until golden and tender.
While potatoes roast, season the steak cubes with smoked paprika, garlic powder, salt, and pepper.
Heat the remaining 1 tablespoon of olive oil in a large skillet over high heat. Sear the steak cubes for 5-7 minutes, turning occasionally, until browned and cooked to desired doneness.
In a small mixing bowl, whisk together the Greek yogurt, minced chipotle peppers, lime juice, honey, and salt until a smooth sauce forms.
Divide the roasted potatoes and seared steak evenly among four meal prep containers.
Top each portion with a generous drizzle of the creamy chipotle sauce and optional fresh cilantro.
