DO-AHEAD TIP: Marinate beef overnight or for at least 4 hours (see recipe).
In a large bowl, combine all ingredients except coconut oil; blend ingredients well with your very clean hands. Cover and refrigerate overnight or for at least 4 hours.
At time of cooking, melt the coconut oil in a large wok or skillet over medium-high heat. Add beef mixture and stir-fry for 6 to 10 minutes or until beef strips are cooked through.
