Assemble all your ingredients before beginning to cook. Remove meat from refrigerator. Pat dry and let rest between paper towels. Allow it to come up to room temperature, about 5 to 10 minutes.
Season meat with salt and pepper.
Heat grape seed oil (or olive oil) and butter over medium-high heat. (Use about 1 to 2 tablespoons of each, depending on size of pan and amount of meat.)
Sauté meat on each side in a single layer until golden brown. Do not crowd. Cook in batches, if necessary.
Remove the sautéed items from the pan and place on a platter. Set platter into a 180°F oven to keep warm.
Add stock to the pan.
Raise heat and cook 2 to 3 minutes until the liquid has reduced by 1/4 to 1/3 of the starting volume, or until the sauce coats the back of a spoon.
To finish the sauce, swirl in a pat of butter to bind and thicken the sauce as well as to add richness and sheen.
To serve, place the cooked meat on individual plates. Nap with a small amount of sauce and serve the remaining sauce on the side at table.
