Spray a loaf pan with cooking spray and set aside.
In a large mixing bowl, combine ground beef, eggs, Naan, ⅔ cup Vindaloo cooking sauce and cheese. It’s easiest to mix it together with clean hands.
Pack the meat mixture into the loaf pan and place on a baking sheet. Bake in the oven for 1 hour, or until beef is cooked thoroughly.
Remove from oven and let cool 10 minutes. Flip onto a serving platter. Spread ⅓ cup Vindaloo sauce over top and garnish with chives. Serve hot. Refrigerate any leftovers.
