1 ½ lbs sirloin steak cut into pieces (3-inch pieces for well done, 4-inch pieces for medium, 5-inch pieces for medium rare
1 pound baby potatoes cut into quarters
1 yellow onion thinly sliced
1 tablespoon olive oil
2 tablespoons chopped fresh parsley
2 tablespoon minced garlic
1 tablespoon Montreal steak seasoning
2 tablespoons butter cubed

Place quartered potatoes in a pot of boiling water and cook for 5 minutes. Drain and place potatoes in a large bowl. Allow to sit for 10 minutes or until they are cool enough to touch.
Add steak, onion, olive oil, parsley, garlic, and Montreal steak seasoning to the large bowl with potatoes.
Place four pieces of aluminum foil (at least 12x12 inches) out on your work surface.
Evenly divide the steak and potato mixture between the four packs.
Top each pack with cubes of butter.
Gently fold the foil over the steak and potatoes, sealing each pack well. (If needed, you can use an additional piece of aluminum foil to lay on top and then seal the edges with the bottom piece of foil.)
Place packs on a hot grill and cook for 8-12 minutes.

Cook time will vary depending on the exact grill temperature, aluminum foil used, and thickness of your steak.
I suggest using a thermometer to check the temperature of the steak after 8 minutes of cooking, helping to reach your desired results.
