I've stumbled onto what I think is the perfect steak marinade. In a bowl, mix 1/2 cup soy sauce, 2 tbsp Sriracha chili sauce, 1/4 cup lemon juice, 1/8 cup fish sauce, 1 clove pressed garlic, 1 small minced onion, and 2/3 tsp black pepper.

Soak the steak in this marinade for about 2 hours, flipping the steak every 30 minutes or so.

Grill it to taste.
