You can buy toasted pine nuts to add to the recipe or you can use raw pine nuts and toast them yourself. Toast the pine nuts before cooking the beef and onions in the pot you’ll use for cooking the ground beef. That minimizes the pots you’ll use and lends a nutty flavor from the pine nuts to the ground beef. Make sure to add the seasoning to the onions and ground beef after they are mostly cooked. That’s because adding seasoning, especially salt, to ground beef too early can draw out the moisture and make the beef less juicy. Add small-diced vegetables to the stuffing. The classic recipe is generally onions, beef and spices along with rice. However, it’s a great recipe for using up leftover vegetables you have in your fridge like tomatoes, zucchini or peppers.
