Prepare the Vegetables: Slice the zucchini and red onion. Halve the cherry tomatoes and set aside the olives and feta cheese for later use.
Cook the Ground Beef: In a large skillet or wok, heat olive oil over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain any excess fat.
Sauté the Vegetables: Add the zucchini and onion to the pan with the beef. Stir occasionally, cooking for about 4-5 minutes, until the vegetables are slightly tender but still crisp.
Add the Tomatoes and Olives: Stir in the cherry tomatoes and olives. Continue to cook for an additional 2-3 minutes until the tomatoes soften.
Season and Combine: Sprinkle in the garlic powder, dried oregano, cumin (if using), salt, and pepper. Stir well and let it cook for another 2 minutes to meld the flavors.
Finish and Garnish: Remove from heat and top with crumbled feta cheese and freshly chopped parsley. Serve hot and enjoy!
