Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Toss zucchini rounds with olive oil, oregano, salt, and pepper in a large bowl until evenly coated.
Arrange zucchini in a single layer on the baking sheet and roast for 18 to 20 minutes, flipping halfway through, until golden and tender.
While zucchini roasts, combine feta, Greek yogurt, olive oil, and garlic in a food processor. Blend until the mixture is light and completely smooth.
In a small bowl, whisk together the honey, lemon juice, lemon zest, and red pepper flakes.
Spread the whipped feta in a thick, even layer onto a serving platter.
Arrange the warm roasted zucchini slices over the feta.
Drizzle the lemon honey over the dish and top with fresh mint and toasted pine nuts.
