Cook the rice according to package directions minus 1/4 cup water. Drain and cool.
Bring 2 cups water and 1/2 tablespoon salt to a boil in a medium saucepan and cook the shrimp for 1 minute. Drain immediately and set aside.
Heat the butter in saucepan and saute the pepper and onion until soft, about 5 minutes.
Preheat oven to 325 degrees F.
In a large bowl, combine the rice, soup, 1 1/2 cups of cheese, shrimp and vegetables. Add salt and pepper, to taste. Mix well. Spray a 9-inch square aluminum cake pan or an 11 by 7-inch glass casserole dish with vegetable spray. Place the mixture in the pan and top with remaining 1/2 cup cheese. Bake for 30 minutes, until bubbly.
