A super tasty and easy meal with Asian inspired flavours that come from ingredients that you likely have in your fridge. To make it a stand-alone meal (minus the lettuce cups), stir in some frozen mixed veggies, cook through and serve with steamed rice.
Cook ground beef, mushrooms and onion and mushrooms in large non-stick skillet over medium-high heat, breaking up beef with back of spoon, until cooked through and much of the liquid has evaporated. Drain if desired. Meanwhile, combine hoisin sauce, soy sauce, rice vinegar, garlic, gingerroot and sriracha sauce. Pour over cooked meat mixture and heat through.
Remove from heat and stir in green onion and sesame oil.
Serve spooned into lettuce leaves and top with peanuts (if using) and additional sriracha sauce.
