Tuna fajitas are a delicious and healthy twist on the classic Mexican dish. Marinated tuna is grilled to perfection and served with sautéed peppers and onions, creating a flavorful and satisfying meal. The tender and flaky tuna pairs perfectly with the smoky and slightly charred vegetables, while the warm tortillas provide a soft and comforting base. Topped with fresh salsa, guacamole, and sour cream, these tuna fajitas are a refreshing and nutritious option for any meal.
