Step 1

Boil potatoes in salted water until tender. Boil green beans in salted water 5 minutes. Drain both and cool. Slice potatoes and tomatoes ¼-inch thick. Preheat oven to 450°.

Step 3

Cut 4 pieces of parchment paper into 34x16-inch pieces. On a flat surface, lay the parchment paper. In the center of half of the parchment paper place a single layer of potato slices (about 1/2-inch larger then the chicken). Add a layer of green beans. Add chicken breast on top of the vegetables. Layer sliced tomatoes, add olives. Drizzle with olive oil. Sprinkle with salt and pepper. Top with thyme.

Step 5

Use a pastry brush to brush egg wash along edges of the paper.  Fold the paper in half over the chicken and vegetables. Crimp the edges to seal. Add another layer of the egg wash to ensure the edges will stay closed. Repeat on the other three packets. Place each packet on a baking pan (2 per pan). Bake 40 minutes. Cut an X in the center of each packet and serve.
