Preheat the oven to 425°F (220°C).
Carefully cut the kernels from each ear of corn and place them on a large sheet pan.
Add the zucchini slices.
Drizzle with olive oil and season with smoked paprika, salt, and black pepper.
Toss everything until evenly coated and spread into a single layer.
Roast for 30 minutes, stirring halfway through if desired, until the corn is lightly charred and the zucchini is tender.
About 10 minutes before the vegetables finish roasting, cook the orzo in salted boiling water until al dente.
Drain the orzo well.
In a small bowl, whisk together the olive oil, lime juice, Dijon mustard, maple syrup (or honey), grated garlic, oregano, salt, and black pepper.
Add the cooked orzo directly to the roasted vegetables.
Pour over the dressing and gently toss until evenly coated.
Fold in the crumbled feta and chopped fresh herbs.
Serve the Roasted Corn Orzo warm with extra lime wedges and additional herbs if desired
