Preheat the oven to 425°F and line a large baking sheet with parchment paper.
In a large bowl, combine the chickpeas, eggplant cubes, cherry tomatoes, minced garlic, olive oil, oregano, salt, and black pepper. Toss until everything is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet.
Scatter the feta cubes over the top of the vegetables and chickpeas.
Bake for 25 to 30 minutes, until the eggplant is tender and the tomatoes have burst.
Remove the pan from the oven and sprinkle with chopped parsley before serving.
