Nonna's Beef Tacos

In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook onion, stirring, until softened, 5-6 minutes. Reduce heat to medium. Add the balsamic vinegar, the brown sugar and a splash of water. Mix well, then cook until dark and sticky, 3-5 minutes. Transfer to a small bowl.

While onion is cooking, combine garlic & herb seasoning and a drizzle of olive oil in a medium bowl. Season, then add beef strips, tossing to coat.

Return frying pan to high heat with a drizzle of olive oil. When oil is hot, cook beef strips, in batches, until browned and cooked through, 1-2 minutes. Transfer to a bowl.

TIP: Cooking the meat in batches over a high heat helps it stay tender.
