Heat olive oil in a large skillet over medium heat.
Add ground beef, breaking it apart with a wooden spoon, and cook until browned.
Toss in the onion and garlic, stirring until fragrant.
Add the bell peppers and zucchini. Stir fry until the vegetables are tender but still crisp.
Season with paprika, oregano, soy sauce, salt, and pepper. Stir well to coat everything.
Serve hot with rice, quinoa, or flatbread, topped with fresh parsley or cilantro.
