• Before starting, preheat the oven to 450°F. 
• Wash and dry all produce.
• Peel, then cut shallot into 1/4-inch pieces.
• Thinly slice mushrooms.
• Remove any brown spots from potatoes, then peel and cut potatoes into 1-inch pieces.
• To a large pot, add potatoes, 2 tsp salt and enough water to cover (by approx. 1 inch) (use same for 4 servings). Cover and bring to a boil over high. 

• Meanwhile, to a large bowl, add half the vinegar, 1/4 tsp (1/2 tsp) sugar and 1/2 tbsp (1 tbsp) oil. Season with salt and pepper. Stir to combine.
• Top with spinach and salad topping mix. Set aside in the fridge until step 6.

• Once water is boiling, reduce heat to medium-high. Simmer uncovered for 10-12 min, until fork-tender.
• Drain and return potatoes to the same pot, off heat. 
• Roughly mash 2 tbsp (4 tbsp) butter and 3 tbsp (6 tbsp) milk into potatoes until slightly mashed. (NOTE: 'Smashed' potatoes will still have a few chunks!) 
• Season with salt and pepper.

• Meanwhile, pat steaks dry with paper towels, then season all over with salt and pepper. 
• Heat a large non-stick pan over medium-high. 
• When hot, add 1 tbsp (2 tbsp) oil, then steaks. 
• Pan-fry for 4-7 min per side, or until cooked to desired doneness.** (NOTE: If steaks brown too quickly, reduce heat to medium.)
• When steaks are done, remove from heat and transfer to a plate. Loosely cover with foil and set aside to rest for 2-3 min.

• Meanwhile, reheat the same pan over medium-high.
• When hot, add 1 tbsp (2 tbsp) oil, then mushrooms.
• Season with salt and pepper. Cook for 5-8 min, stirring often, until softened.
• Add garlic puree, shallots, flour and 1 tbsp (2 tbsp) butter. Cook for 1-2 min, stirring often, until shallots soften slightly.
• Reduce heat to medium, then stir in 2/3 cup (1 1/3 cups) water, broth concentrate, remaining vinegar and any beef resting juices.
• Bring to a simmer. Cook for 3-4 min, stirring occasionally, until gravy thickens slightly.

• Toss salad.
• Thinly slice steaks.
• Divide steaks, salad and smashed potatoes between plates.
• Spoon mushroom gravy over steaks and potatoes.
