Chicken With Purple Onions - cooking recipe

Ingredients

2 lbs boneless skinless chicken breasts
2 large purple onions
8 ounces grated parmesan cheese (fresh is best)
1/2 tablespoon cayenne pepper (to taste)
2 tablespoons parsley (fresh or dried- for color)
Dressing (use parmesan cheese dressing)
1/4 cup milk
1/3 cup mayonnaise (not miracle whip)
1/4 cup grated parmesan cheese (I use the dried version for this)
1 teaspoon white wine vinegar
1/4 teaspoon Worcestershire sauce

Preparation

Combine dressing ingredients and preheat oven to 425 degrees.
Peel onions. Cut into six 1/2\" thick slices and place on an ungreased baking sheet. (You want to cut them in the same direction that do when you trim off the ends so that you see the rings of the onions.) (Hope that makes sense). Save onion scraps for another use if desired.
Trim chicken of any visible fat and place in a single layer on onion slices, trimming and filling in as needed on each onion slice. (It's okay if the chicken hangs over the onion slightly).
Drizzle about 1 tablespoon dressing mixture over each serving.
Generously sprinkle on parmesan cheese and cayenne pepper to taste. Top with parsley. Bake at 425 degrees for about 30 minutes.
