In a large skillet over medium heat, add the remaining tablespoon of oil and butter. Add the chopped onion and garlic, and sauté for a minute. Then, add the sun-dried tomatoes.
Stir in the orzo pasta and cook for about a minute. Add the chicken broth and cook for 5-7 minutes until the liquid is almost absorbed.
