1. 1. Cook the Beef: Heat the olive oil in a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain any excess fat, if needed.

2. 2. Add the Aromatics: Stir in the diced onion and minced garlic. Cook for 2-3 minutes, until the onion is softened.

3. 3. Incorporate the Vegetables: Toss in the chopped zucchini, red bell pepper, and halved cherry tomatoes. Cook for 5-6 minutes, until the vegetables are tender but still crisp.

4. 4. Season with Flavor: Stir in the sliced Kalamata olives, dried oregano, ground cumin, paprika, salt, and black pepper. Mix well and cook for an additional 1-2 minutes to blend the flavors.

5. 5. Finish with Freshness: Remove the skillet from heat and stir in the lemon juice, chopped parsley, and crumbled feta cheese.

6. 6. Serve and Enjoy: Savor this flavorful Mediterranean Ground Beef Stir Fry on its own or serve it over a bed of fluffy rice, quinoa, or alongside warm pita bread.
