Step 1

For the Salisbury steak: Heat 3 tablespoons of the olive oil in a large saute pan over medium-high heat. Add the diced onions and 1 teaspoon salt. Cook, stirring occasionally, until the onions are translucent, about 5 minutes. Add half of the minced garlic and cook for another 1 to 2 minutes until fragrant. Set aside to lightly cool.

Step 2

In a medium bowl, add the ground beef, panko, chicken stock, ketchup, Worcestershire sauce, egg, 2 tablespoons of the Dijon and the sauteed onions and garlic. Reserve the pan that the onion and garlic were cooked in. Combine the ground beef mixture until all ingredients are fully incorporated.

Step 3

Turn the saute pan back on to medium-high heat and add 2 tablespoons of olive oil. Take a small amount of the meat mixture and cook a tester patty to check for seasoning; adjust the remaining meat mixture with more salt if necessary. Form the remaining meat mixture into 4 equally-sized oval patties, patting firmly, each 1/2 to 3/4 inch thick. Add another tablespoon of olive oil to the pan and cook the patties over medium-high heat until golden brown, 2 to 3 minutes per side. Remove the patties onto a sheet tray and discard any excess fat from the pan.

Step 4

To make the gravy, return the pan to medium-high heat and add the remaining 2 tablespoons olive oil. Add the sliced onions and cook, stirring occasionally, until the onions are translucent, about 5 minutes. Add the remaining garlic and cook 1 to 2 minutes. Add the mushrooms and cook until brown and softened, another 5 minutes. Add the flour and cook for 1 minute. Add the beef stock and remaining 2 tablespoons Dijon. Bring the mixture to a boil, then reduce to a simmer and cook until the gravy has thickened slightly, 3 to 5 minutes. Add the Salisbury steaks back into the gravy and simmer for 5 minutes.

Step 5

For the peas, carrots and peppers: To a medium saute pan, add the carrots, 1/2 cup of the chicken stock and a generous pinch of salt. Turn on the heat to medium high and cook until the carrots are slightly tender, 8 to 10 minutes. Add the red bell pepper and remaining 1/4 cup chicken stock and cook until the chicken stock has mostly reduced, about another 5 minutes. Add the frozen peas and butter and swirl until the butter has melted, then turn off the heat and set aside.

Step 6

For the garlic mashed potatoes: Heat the heavy cream in a small saucepan over low heat.

Step 7

In another saucepan, add the potatoes and garlic and cover with cold water. Generously season the water with salt. Bring to a boil, then reduce to a simmer until the potatoes are fork tender, 15 to 20 minutes. Drain the potatoes, then return them to the pan. Using a hand mixer, blend the potatoes and add half of the butter. Then add some of the heated cream and the rest of the butter. Continue to mix, gradually adding more heavy cream until you reach the desired consistency for your mashed potatoes. You may not need to use all of the cream.

Step 8

To plate: Plate the Salisbury steaks and smother with the gravy, then garnish with the sliced chives. Serve alongside the peas, carrots and red peppers and garlic mashed potatoes.
