So, my wife invited over some neighbors, I thought it was last night, but it's tonight. Whatever, She picked up a tenderloin at Costco and I already seasoned it, which is fine. She was talking about having beef tacos with the leftovers and I thought "I trained her pretty good."
I'm still debating how to cook the steak. I cut it into halves because she wants her steak blu rare, rarer than most folks including me. It's a lot easier to cook it in the oven with the T probe than on the grill. One option is sear it on the grill and transfer it to the oven, another option it turn on broil in the oven for a few and then cook it.
