In a large skillet or pan, heat olive oil over medium-high heat. Add the ground beef and cook for 5-7 minutes until browned and crumbles easily.
Once browned, add sliced bell peppers and zucchini to the skillet. Cook for 3-5 minutes until vegetables are tender yet still vibrant.
Stir in soy sauce, minced garlic, and ginger; cook for another minute until aromatic.
