Prepare the vegetables by washing and chopping the cherry tomatoes, bell peppers, red onion, and zucchini into bite-sized pieces. Preheat your oven to 400°F (200°C). Arrange them evenly on a large baking sheet.

Drizzle the chopped vegetables with olive oil, add minced garlic, oregano, salt, and pepper. Toss until everything is well coated.

Place the baking sheet in the preheated oven and roast for 25-30 minutes until tender and caramelized, stirring halfway through.

Remove from oven and sprinkle crumbled feta cheese over the hot vegetables, allowing it to soften.

Garnish with fresh chopped parsley and serve warm from the pan.
