Before starting, preheat the oven to 450˚F. Wash and dry all produce. Cut potatoes into 1-inch pieces. Add potatoes, 2 tsp salt and enough water to cover (by approx. 1 inch) to a large pot (use same for 4 ppl). Cover and bring to a boil over high heat.Once boiling, reduce heat to medium. Simmer uncovered, until fork-tender, 10-12 min. 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, to taste.

Meanwhile, heat a large non-stick pan over medium-high heat.While the pan heats, pat chicken dry with paper towels. Season with 1 tsp (2 tsp) chicken stock powder, salt and pepper.When the pan is hot, add 1/2 tbsp (1 tbsp) oil, then chicken. Cook until golden-brown, 1-2 min per side.Remove the pan from heat. Transfer chicken to an unlined baking sheet.Roast in the top of the oven until cooked through, 8-10 min.**

Meanwhile, roughly chop spinach.Peel, then mince or grate garlic.Thinly slice chives.

When potatoes are done, heat the same pan (from step 2) over medium.When hot, add 1 tbsp (2 tbsp) butter, then swirl the pan until melted. Add garlic and Cream Sauce Spice Blend. Cook, stirring often, until fragrant, 30 sec.Gradually whisk in 3/4 cup (1 1/4 cups) water, cream cheese and remaining stock powder. Bring to a simmer, whisking often, until cream cheese is mostly combined. (TIP: It's okay if there are bits of cream cheese. The sauce will smooth out in the next step.)

Once simmering, add spinach to the pan with sauce. Cook, stirring often, until sauce thickens slightly, 3-4 min.Add Dijon and any juices from the baking sheet with chicken. Season with salt and pepper, to taste. Cook, whisking often, until Dijon is incorporated, 30 sec.Remove the pan from heat.

Thinly slice chicken.Add half the chives to smashed potatoes, then stir to combine.Divide smashed potatoes between plates, then top with chicken. Spoon sauce over chicken and potatoes. Sprinkle remaining chives over top.
