[Steak Tips]
2. Seal, squeezing to expel any air, and let meat marinate for 2 hours.
3. When ready to cook, drain and season meat with salt and pepper.
4. Set up your grill for direct high heat. To grill meat, sear on one side until nicely browned, 4 - 6 minutes. Turn meat and grill until it reaches desired doneness (4 - 6 minutes more for medium rare).
5. Cook onions in a grill pan, stirring occasionally, until golden, about 10 minutes. Or cook onions directly on grill grates away from direct heat, carefully turning once, for 8 - 10 minutes total cooking time.
