Chinese Chicken Salad

I have made this salad several times in the past few weeks.  It really is a great, fresh tasting salad and several people have asked for the recipe.  

Dressing:
1 cup canola oil
1/2-3/4 cup rice vinegar, seasoned.  I like Marukan brand
1/2 cup sugar
salt and pepper

Salad:
1 head of cabbage--shredded
2 bunches of cilantro, cut up into pieces
5 cooked and shredded chicken breasts (or if you want to save time, I often use rotisserie chicken) 
1 bunch green onion
2 packages slivered almonds
