Preheat the oven to 425° F.
Place the potatoes, lemon wedges, garlic cloves, rosemary sprig, and oregano on a baking sheet and sprinkle with salt and pepper. Drizzle with about 1/4 cup olive oil and toss so that everything is coated.
Roast for about 30-40 minutes, or until golden and tender.
For the feta layer, combine the feta, milk, honey, and lemon juice in a blender and blend until creamy. Add additional lemon juice if needed.
Spread the feta out onto a platter in an even layer.
Remove the rosemary spring and garlic from the potatoes and then place the roasted potatoes over the feta.
Sprinkle the top of the potatoes with fresh herbs, and parmesan cheese.
Add a sprinkle of red pepper flakes if desired and a sprinkle of flakey sea salt.
