Preheat the oven to 425°F (220°C).
Carefully remove the corn kernels from the cobs and place them on a large baking sheet with the zucchini.
Drizzle with olive oil and season with smoked paprika, salt, and black pepper. Toss well.
Spread everything into an even layer and roast for 30 minutes until the corn is lightly charred and the zucchini is tender.
Meanwhile, cook the orzo in salted boiling water until al dente. Drain well.
Whisk together olive oil, lime juice, Dijon mustard, maple syrup, grated garlic, oregano, salt, and pepper.
Add the cooked orzo directly to the roasted vegetables.
Pour the dressing over everything and gently toss to coat.
Fold in the feta cheese and chopped herbs.
Serve Roasted Corn Orzo with Zucchini and Feta warm with extra lime wedges and fresh herbs if desired.
