Tri tip, orzo with pesto, olives, feta and pinenuts, salad

I roasted the tri tip, but I think next time I will grill it. The orzo is the following recipe--also great with grilled chicken!

Orzo:

1/4 cup prepared pesto
1 cup kalamata olives, chopped
1/4 cup pine nuts
1/4 cup feta cheese
splash red wine vinegar
1/2 pound hot cooked orzo

While orzo is cooking, assemble the rest of the ingredients in a serving bowl. Drain orzo and toss with pesto mixture. Adjust seasonings and serve.
