Add all of the ingredients for the vinaigrette to a medium sized bowl and whisk well until thoroughly combined. Once finished, set aside.
Prepare all the salad ingredients by slicing, chopping, crushing, rinsing, and crumbling.
NOTE: The ingredients from the above vinaigrette and salad sections have now been used. The below ingredients will come from the "For the Orzo" ingredient section above.
Warm a large skillet over medium-high heat. Add the butter and olive oil. Then add the orzo and the chopped onion. Cook for about five minutes until the onion is somewhat soft and the orzo begins to lightly brown.
Add the broth, lemon juice, salt, and pepper to the skillet. Simmer and stir for about 10 minutes or until the orzo is al dente. When finished, turn off heat. If you have excess liquid, drain it from the pan.
Allow the orzo to cool completely in the refrigerator. Once cooled, transfer the orzo to a large bowl and add all the vegetables and dressing to the bowl as well. Mix all the ingredients together and season to taste, if needed.
Plate and serve. Enjoy!
