Spice up the tri-tip with all of the above spices. If you have fresh garlic, make couple of holes and insert the garlic in meat. Put the tri-tip in a crockpot in the morning on low, before you leave to work and it will be done when you get home. The meat shreds real good. If you have any left over, make shredded beef tacos, burritos or taquitos the following day.
