South Texas Steak Fajitas are a delicious and flavorful Tex-Mex dish made with marinated grilled steak, sautéed peppers and onions, and served with warm tortillas. The steak is marinated in a mixture of lime juice, garlic, cumin, and chili powder, which adds a tangy and spicy flavor. The peppers and onions are cooked until tender and slightly caramelized, adding a sweet and savory element to the dish. These fajitas are perfect for a weeknight dinner or a festive gathering with friends and family.
