Steak with Pasta and Blue Cheese

This dish is such an amazing treat!  The sauce on the pasta is very creamy and full of flavor.  Make sure at the end you sprinkle some blue cheese for that extra flavor.  A word of caution about this dish: be careful when grilling since the meat is marinated in a mixture containing olive oil.  You need to drain it well and cook it over a low fire, otherwise there is too much grease and that would cause the flames to flare up quite a bit.  Anyway, enjoy this amazing and simple dish!
-2 lbs boneless beef steak, cut into large strips
-1 cup extra virgin olive oil
-1/4 cup red wine vinegar
-1 tsp salt
-1/2 tsp pepper
-1 Tbs lemon juice
-1 lb linguine pasta
-2 cups fresh spinach, chopped
-32 oz Alfredo sauce (homemade or store-bought; they both work just fine)
-about 6 green onions, cleaned and chopped
-6 Tbs blue cheese, divided
-1 large tomato, chopped
In large bowl, combine oil, vinegar, salt, pepper, and lemon juice.  Mix well, add steak strips, cover and let it marinate in the fridge for at least 1 hour.
Drain steak well and grill to your desired doneness.  Let it rest for a few minutes, then cut into small slices.
Meanwhile, cook the pasta according to package directions.  Drain and set aside.
While pasta and steak are cooking, make the sauce: heat the Alfredo sauce in large saute pan.  Add green onion, spinach and 3 Tbs of the cheese.  Cook until heated through.  Add drained pasta and mix well (sauce will thicken as it stands).
To serve, place some pasta with sauce on plate.  Top with steak slices, remaining cheese and chopped tomatoes.  Enjoy!
