Toss the diced chicken with onion powder, thyme, paprika, salt and black pepper until the chicken is well coated in the seasoning.
1 large chicken breast, 1 tsp onion powder, 1 tsp thyme, 1/2 tsp paprika, 1/2 tsp salt, 1/2 tsp black pepper
Melt one tablespoon of oil in a large skillet or deep sauté pan over medium heat. Add the chicken and cook until lightly browned and cooked through, about 5 minutes. Remove the chicken from the pan and set aside.
1 tbsp olive oil
Add the butter to the pan, then add the diced onion and celery. Cook for 3-4 minutes, or until the veggies are tender. Add the garlic and cook for one more minute.
3 tbsp butter, 1 small yellow onion, 2 celery stalks, 2 garlic gloves
Add the orzo to the pan, stir and toast for one minute. Pour in the chicken broth and bring to a gentle simmer. Reduce heat to medium-low and cook, stirring frequently, until the orzo is tender and most of the liquid is absorbed, about 7-8 minutes.
1 1/2 cups orzo, 3-3 1/2 cups chicken broth
Stir in the frozen mixed vegetables, half and half (or milk) and the cooked chicken. Stir and simmer for another 2–3 minutes, or until the orzo is tender and everything is heated through.
1 cup frozen mixed veggies (peas, carrots, green beans, corn), 1/2 cup half & half
Taste and adjust seasoning as needed. Serve warm.
