Preheat the oven to 400 degrees.

Prep your meat and vegetables. Cut the florets off of the heads of cauliflower and broccoli, and cut the asparagus spears into bite sized pieces. You want to use fresh vegetables and not frozen. Cut the sirloin steak into bite sized pieces as well.

Place the sirloin steak pieces into a mixing bowl, and add in the rosemary, basil and thyme.

Mix in salt and pepper to taste, and toss the meat well to incorporate the seasoning.

Heat 1 tablespoon of oil in a skillet over medium-high heat. Once hot, add in the sirloin steak in a single layer, and quickly sear it on all sides. Remove it from the heat.

In a large mixing bowl, combine the cauliflower, broccoli, asparagus and onion.

Pour a tablespoon of olive oil over the vegetables, and add salt and pepper to taste. Mix the vegetables together to coat them all well.

Place a large sheet of aluminum foil onto a flat surface. Place a handful or two of the vegetables onto the center of the foil.

Top the vegetables with some of the seared meat. Top with more salt and pepper to taste if desired.

Fold the two horizontal sides of the aluminum foil up, and roll them closed a few times at the top. Fold in the side of the foil to form a closed packet. This will allow your meal to steam when in the oven. Leave some room for air in the packets, to not roll them too tightly.

Repeat steps 8-10 with the remaining packets, until you have six packets completed.

Bake for 15-20 minutes, remove the packets from the oven, open and serve.

Enjoy!
