This shows the fresh ingredients ready for preparation.
Directions
- In a bowl, combine the vinegar, minced garlic, oregano, salt, and pepper. Mix well and marinate the steaks in this mixture for at least 30 minutes to enhance the flavors.
- Heat the olive oil in a pan over medium heat. Remove the steaks from the marinade (be sure to reserve the marinade) and cook them for about 3-4 minutes on each side until browned. Once cooked, remove them from the pan and set aside.
- In the same pan, add the sliced onions and sauté until they become soft and translucent, approximately 5-7 minutes. If desired, you can also add sliced bell peppers during this step for added flavor and color.
- Return the steaks to the pan, along with the reserved marinade. Cook for an additional 3-5 minutes, allowing all the flavors to meld together beautifully.
- Serve hot with lime wedges on the side and your choice of side dish, such as rice or a fresh salad.
Tips & Variations
- Ingredient Substitutions: If sirloin isn’t available, you can use flank steak or ribeye for a different flavor and texture. For a lighter option, try using chicken breasts instead of steak.
- Optional Variations: Feel free to add other vegetables like mushrooms or zucchini along with the onions for a colorful stir-fry. You can also experiment with different herbs in the marinade such as thyme or rosemary.
- Storage or Reheating Tips: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm in a pan over low heat until heated through or microwave with a splash of water to keep the meat moist.
