Preheat the oven to 400°F.
Pat dry the cod filets with a kitchen towel and set them aside.
In a small bowl or plate, mix the seasonings: Greek Mediterranean blend, salt, and black pepper. Sprinkle half of the prepared seasonings over the cod filets. Drizzle a tablespoon of olive oil over the cod filets and set them aside.
Add the veggies to a baking dish: cherry tomatoes, asparagus, artichokes, olives, and red onions. Sprinkle the remaining seasonings and oil over the veggies and toss well.
Place the baking dish in the oven for 10 minutes. After 10 minutes, lay the cod filets over the veggies and bake for an additional 10-12 minutes, until the cod is cooked through.
Remove the baking dish from the oven and set it aside to rest for 10 minutes. Garnish with feta cheese and fresh basil, then serve the cod filets along with the roasted vegetables.
