BBQ'ed or grill-roasted tri-tips on the charcoal grill with a handful of oak chips for smoke. They took about a half an hour to cook, turning every 4-5 minutes. I basted them with a mix of olive oil, red wine vinegar and crushed garlic every time they were turned. They turned out super juicy and really tasty. Plus choice tri-tips are only $6.99/lb, so it's one of the cheaper cuts of beef you can grill.
