Cook the tortellini according to the package instructions; rinse, drain and set aside. (Tip: Toss the pasta in 1-2 Tbsp of milk to prevent it from sticking together once rinsed.)
For the Steak
Using a small bowl, add all marinade ingredients (soy sauce, olive oil, lemon juice, Worcestershire sauce, dried basil, dried parsley, garlic powder and pepper).
Place steaks in a small baking dish. Pour marinade on top, turning to coat both sides. Cover with plastic wrap and refrigerate for at least 30 minutes, or up to 8 hours.
Preheat grill to high heat.
Grill steaks for 3-4 minutes per side (medium-rare to medium). Turn gas off (or close grill air vents) and continue grilling until steaks reach desired doneness (~4-8 more minutes depending on thickness of steaks).
Transfer steaks to cutting board and let stand for 5 minutes.
Slice steaks against the grain.
Divide pasta evenly onto plates and top with tomatoes, red onion, blue cheese, bacon and sliced ribeye steaks. Garnish with green onions and blue cheese dressing before serving.
