1Mix the pork, egg, Parmigiano-Reggiano cheese, onion powder, tarragon, and salt until everything is well incorporated; form into meatballs the size of a tablespoon. Spread bread crumbs into a shallow dish; roll meatballs in bread crumbs to coat.
2Heat the olive oil in a skillet over medium heat. Cook meatballs in hot oil until golden brown on all sides, 3 to 5 minutes. Add white wine half a glass at the time; cook at a simmer until the wine is reduced to a nice thick sauce, about 15 minutes.
