Rinse rice until water runs clear
In a large pot, cook rice according to your package instructions, adding curry powder to the water. Be careful to not overcook—al dente is best.
Once the rice is cooked, immediately transfer to a large bowl to help lower the temperature. (This is so it doesn't continue cooking and get mushy and stuck together.)
While rice is cooling, chop the celery, red pepper, dill pickles, onion, and chicken
When rice is cool, add chopped vegetables, chicken, and peas. Mix well.
Make dressing in a small bowl by mixing together mayonnaise, Miracle Whip, salt, and pepper
If the dressing seems thick, thin it with a little dill pickle juice
Pour dressing over the salad; toss gently to coat all ingredients
Taste, and season with more salt and pepper if necessary
Chill before serving
