Start the prep by preheating oven to 450 degrees. Peel and mince garlic, and set aside. And finely chop onion to ¾ cup, set aside.
Remove pork chops from package and place on a cutting board and cover with a sheet of plastic wrap. Pound with a meat mallet until both chops are an even thickness and about 1/4 in thick. Remove plastic wrap and pat dry with a paper towel, sprinkle each side with a dusting of flour, salt and pepper, then set aside.
To make the couscous, start by melting one tablespoon butter on medium heat in a sauce pot, allowing it to melt halfway. Add garlic, and half of the chopped onions and season with salt and pepper. Stir while cooking for approximately 5 minutes, or until translucent and aromatic. Add dry couscous to the pot and stir well. Then stir in the chicken stock concentrate with ¾ cups of water. Add salt, bring to a rapid boil for 30 seconds and then remove from heat and set aside on another burner with a lid until you are ready to plate.
To cook the pork chops, heat a drizzle of vegetable oil in a large frying pan or skillet at medium-high heat. Once heated, add the pork chops and cook for 5 minutes on each side, or until a nice golden brown crust forms around the edges. When pork chops are done, take them out of the pan and set them aside on a dish.
While the pork chops are browning, place the green beans on a baking sheet with a drizzle of oil, salt, and pepper and bake until softened in the oven for 10-15 minutes, or until preferred doneness. Remove from the oven when done and set aside.
In the same pan you used for the pork chops, add another drizzle of vegetable oil at medium heat and add the rest of the chopped onions with a sprinkle of salt and pepper. Continue cooking for 5 minutes, while stirring, until translucent and aromatic. The onion should become soft and slightly caramelized, and not crispy. Once they become soft add the soy sauce along with ¼ cup of water. Mix well and cook until the sauce thickens slightly, approximately 2-3 minutes.
Remove the pan from heat and add in the sour cream with 1 tbsp butter, stirring well, until thoroughly combined. Add any additional salt and pepper to taste.
The cooking is now done and we are ready to plate!
Place a big scoop of the couscous on each plate and lay a pork chop over the top. Cover the pork chops evenly with the pan sauce and finish the dish by adding the green beans on the side.
