Preheat your oven to 400°F and line a baking sheet with parchment paper.
Cut the cauliflower into small florets and dice the red bell pepper into one-inch pieces.
In a large bowl, toss the cauliflower and peppers with olive oil, sea salt, black pepper, garlic powder, and dried oregano until evenly coated.
Spread the vegetables in a single layer on the baking sheet and roast for 20 to 25 minutes until tender and caramelized at the edges.
While the vegetables roast, bring a small pot of water to a boil, carefully lower in the eggs, and simmer for 6.5 minutes for a jammy yolk.
Immediately transfer the eggs to an ice bath for 3 minutes, then gently peel and slice them in half.
In a small bowl, whisk together the Greek yogurt and lemon juice until smooth, then spread it as a thick base in your serving bowl.
Top the yogurt with the warm roasted vegetables and the halved eggs.
Finish the bowl by sprinkling with crumbled feta cheese and hemp hearts for added texture and protein.
