Heat oil in a medium sauté pan. Toss chicken chunks with salt and pepper and brown, 3-5 minutes, until the outside is golden. (They will not be cooked through.) Remove from heat.
In a medium saucepan, mix tomatoes, tomato paste, and spices. Add water and broth, and bring to a simmer. Simmer, uncovered, over medium heat for 5 minutes.
Grease a 9x13 casserole dish. Place the dry pasta in the bottom of the dish. Sprinkle ½ c of Parmesan over the pasta. Pour the sauce over the pasta and cheese. Nestle the browned chicken pieces evenly over the sauce.
Cover the dish with aluminum foil and bake for 20 minutes, until you start to see bubbles forming around the edges.*
Remove the dish from the oven and top the pasta with the remaining ¼ c of Parmesan cheese and bread crumbs.
Return the dish to the oven and bake, uncovered, 5-10 minutes, or until the cheese is melted and the crumbs are golden.
Remove the dish from the oven. Tent it loosely with aluminum foil and let it stand for 10 minutes before serving.
Notes
*To make ahead: Cover the dish with aluminum foil and refrigerate up to 24 hours. When you are ready to bake the pasta (roughly 1 hour before you would like to eat), place the covered dish from the fridge into the oven as it preheats to 400?F. Bake, covered, for 30 minutes, until the edges are bubbly. Continue with the recipe as directed above.
