Instructions

1. Bring a medium pot of salted water to a boil. Cut potatoes into 1-inch pieces. Add potatoes to boiling water and cook until tender, about 10-12 minutes. Drain and return to pot. Cover to keep warm.
2. While potatoes cook, pat steak dry with paper towels and season generously with salt and pepper. Heat 1 teaspoon cooking oil in a large skillet over medium-high heat until shimmering. Add steak and cook until browned and cooked to your liking (about 3-4 minutes per side for medium-rare). Remove steak to a plate and let rest.
3. Reduce heat to medium. Add cream sauce base and Dijon mustard to the skillet, scraping up any browned bits. Cook, stirring, until sauce thickens slightly, about 1 minute. Remove from heat.
4. In a small bowl, whisk together balsamic vinegar and olive oil. Add mixed greens, shredded carrots and sliced tomato. Toss to coat.
5. Slice steak against the grain. Serve steak with creamy mustard sauce drizzled on top, a pat of garlic herb butter melting over the steak and the buttery potatoes and salad on the side.
