1Heat the olive oil a medium frying pan over medium heat. When it shimmers, add the onion, garlic, and coriander, then season with salt and pepper to taste. Cook until the vegetables are softened, about 3 minutes.
2Add the water and chicken, reduce the heat to medium low, cover, and simmer, turning the chicken once, until the chicken is cooked through, about 25 minutes. Remove the chicken to a cutting board and set aside until cool enough to handle, then shred into bite-sized pieces.
3Meanwhile, add the orzo to the poaching liquid and simmer, stirring occasionally, until the pasta is al dente and all the liquid has been absorbed, about 10 to 15 minutes. Remove the orzo to a large, nonreactive bowl and stir in the maple syrup, vinegar, cilantro, pomegranate seeds, and shredded chicken. Season with salt and pepper to taste.
