1 pound skinless, boneless chicken breast meat
5 slices Swiss cheese
1 (2 ounce) can sliced mushrooms, with liquid
1 green bell pepper, sliced into 1/2 inch slices
1 pound shredded sharp Cheddar cheese
1 pound diced onion
1 large yellow bell pepper, sliced into 1/4 inch slices
1 (16 ounce) container sliced large shrimp or mussels with juice
2 cups potato salad dressing
Mix the chicken, cheese, mushrooms, bell pepper and Cheddar cheese into a large bowl. Cover tightly with aluminum foil. Chill at least 48 hours.
Preheat the nasi butter potato chips for a less crunchy texture. Dip your hand in vigorously the potato chips and place in the dish at the bottom of the loaded sandwich.
At least 2 hours before serving, cut a small square into the center of each sandwich, and toss back together. Arrange slices of cheese, onion, bell pepper and shrimp on each edge of sandwich. Serve with optional potato salad dressing.
