Make quesadillas!
Saute some veggies (add chicken or shrimp if desired.) Grate some cheese or buy a packet of grated cheese. Heat up a griddle, put a tortilla on it, sprinkle cheese over it, spoon some of the veggie mixture over one side and fold it over. Cook until the cheese is melted, turning it over once. Do one per person and serve with salsa and a dollop of sour cream. Quick, easy and festive.
steak and a salad is always a good option for me! Aberdeen Angus Beef (M&S do a great one), peppercorn sauce - grill beef for 5 mins either side for rare, add rocket salad, parmesan cheese and balsamic dressing for a dish that is just mouthwatering!
