Tri Tip Marinade

I searched the internet for a way to make my Tri Tip. Last time I made it, it was dry & didn't have much flavor. So after searching, I came up with my own recipe...

I took 1/2 an onion, 4 garlic cloves, olive oil, apple cider viniger, soy sauce & rosemary. Blended it all in the blender and marinated it. Then put it on the bbq, low & slow. It turned out Delish!!! Served it up with baked yams, PERFECT!
