Did a london broil this weekend for the first time and it was great! I used a store bought marinade and let it sit in that overnight then smoked it at about 250 for 2hours and took it out when it was at 155. I sliced it as thin as I could then we made fajitas with the meat, turned out great. Using the rest tonight for stir fry. Thanks for the tips on london broils, not sure I got a good deal though it was $4.99/lb.
