Peel, then thinly slice half the shallot. Finely chop remaining shallot. Halve Brussels sprouts (if larger, quarter them).Add Brussels sprouts and sliced shallots to a parchment-lined baking sheet. Drizzle 1 tbsp (2 tbsp) water and 1/2 tbsp (1 tbsp) oil over top. Season with half the garlic salt and pepper, then toss to coat. (TIP: Adding water to Brussels sprouts helps them steam while roasting!)Roast in the middle of the oven until tender, 16-20 min.

Meanwhile, pat steak dry with paper towels, then season with truffle salt and pepper.Heat a large non-stick pan over medium-high heat. When hot, add 1 tbsp (2 tbsp) oil, then steak.

Meanwhile, reheat the same pan over medium. When hot, add 1 tbsp (2 tbsp) butter, then remaining shallots. Cook, stirring often, until tender, 2-3 min. Sprinkle Gravy Spice Blend over shallots. Cook, stirring often, until coated, 30 sec. Stir in 1 cup (1 1/2 cups) water and broth concentrate. Bring to a gentle boil.Once boiling, cook, stirring often, until gravy thickens slightly, 3-4 min. Remove from heat, then cover to keep warm.

When steak is done, transfer to a cutting board, then cover loosely with foil. Let rest for 5 min.When potatoes are tender, drain and return them to the same pot, off heat. Roughly mash sour cream, remaining garlic salt, 2 tbsp (4 tbsp) milk and 2 tbsp (4 tbsp) butter into potatoes. Season with pepper, to taste.
