In a mixing bowl, dissolve yeast in water. Stir in basil, Parmesan cheese, tomato paste, sugar, oil, salt, pepper flakes and 2 c. flour. Stir in enough remaining flour to form a stiff dough. Turn onto a floured surface; knead until smooth and elastic, about 3-5 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
