Preheat oven to 350 degrees. Spray a 9x13 inch casserole dish with cooking spray. Set aside.
In a large pot cook the pasta according to directions and cook until al dente. Drain. In a medium sized saucepan add the olive oil, mushrooms, garlic, and peas. Cook until tender. Add the flour and cook for an additional minute.
