To make the meatballs: Lightly oil a broiler pan. Crumble the ground beef into a large bowl. Add the breadcrumbs, eggs, parsley, milk, fish sauce, Worcestershire sauce, Romano, garlic, and pepper. Using your hands, mix well, but do not compact the mixture or the meatballs will be tough. Using about 3 tablespoons per meatball, shape into 24 equal balls and transfer to the prepared broiler pan.
Position the broiler rack about 6 inches away from the heat source and preheat the broiler in high.
Broil the meatballs, turning once or twice, until browned and cooked through, about 10 minutes. If the meatballs are browning too quickly, move them farther away from the heat source.
For each serving, place 3 meatballs in a flameproof bowl or single serving skillet. Top with a spoonful of red sauce, and add a generous dollop of ricotta. Return to the broiler and heat until the ricotta melts, about 30 seconds. top each with a fresh basil leaf, drizzle with oil and serve.
