Before starting, wash and dry all produce. Peel, then cut potatoes into 1/2-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. Mash 2 tbsp butter and 3 tbsp milk (dbl both for 4 ppl) into potatoes until creamy. Season with salt and pepper, to taste.

Meanwhile, add pork, breadcrumbs, half the Dijon, half the Worcestershire sauce and 1/4 tsp salt (dbl for 4 ppl) to a medium bowl. Season with pepper, then combine. Form pork mixture into 2 equal-sized, 1-inch-thick patties (4 patties for 4 ppl). Heat a large non-stick pan over medium heat. When hot, add 1/2 tbsp oil (dbl for 4 ppl), then patties. Cook until golden-brown, 3-4 min per side. (NOTE: It's okay if patties don't cook all the way through in this step.) Transfer patties to a plate.

Meanwhile, add vinegar, remaining Dijon, 1/2 tsp sugar and 1 1/2 tbsp oil (dbl both for 4 ppl) to a large bowl. Season with salt and pepper, to taste, then whisk to combine. Peel, then cut shallot into 1/4-inch pieces.Cut tomato into 1/2-inch pieces.

Return the same pan (from step 2) to medium. Add 1 tbsp butter (dbl for 4 ppl), then swirl the pan until melted. Add shallots. Cook, stirring occasionally, until softened, 2-3 min. Sprinkle Gravy Spice Blend over shallots, then stir until coated, 30 sec. Gradually whisk in 3/4 cup water (dbl for 4 ppl), broth concentrate and remaining Worcestershire sauce until combined. Bring to a gentle simmer.

Once gravy is simmering, return patties to the pan, then reduce heat to medium. Cover and cook, stirring occasionally and flipping patties halfway, until cooked through, 3-4 min.** (TIP: Add water, 1 tbsp at a time, if gravy reduces too much!) Season with salt and pepper, to taste.

Add spring mix and tomatoes to the bowl with vinaigrette, then toss to combine. Divide mash and patties between plates, then spoon shallot gravy over top. Sprinkle salad topping mix over salad, then serve alongside.
