These fresh and flavorful steak fajitas, marinated in lime juice, garlic and old el paso taco seasoning mix, are served with grilled peppers and onions for a quick and complete meal thats totally restaurant quality (but value priced). The cost-effective flank steak can be marinated up to ten hours ahead, so this is also a delicious way to get ahead of a busy day. When dinner rolls around, all it takes is a little chopping and a hot grill pan (or grill, if youve got one) to cook up this succulent and bright meal. Oh, and did we mention, this recipe comes in at 330 calories per serving? So what are you waiting for? Dinner awaits
