I have no recipe for this, I don't even know if there is a recipe or a name for this dish. I cooked it several times and I love it. You can use pork, turkey or chicken.
Spray a large pan with oil.
Dry meat cubes on all sides with a towel. Season liberally with salt and pepper. Sear in batches to develop a nice crust all over. When meat is cooked add 1 clove of garlic, crushed. Mix well and add mustard to the meat. Stir to coat each piece of meat with mustard and cook for one more minute. Remove from the pan and serve hot with salad
