In large bowl, dissolve yeast and sugar in warm water. Stir in cereal mixture, oil, salt, ground peppercorns, cheese and enough of the flour to make a soft dough. Place dough on lightly floured surface; knead about 5 minutes or until smooth and springy. Place dough in greased bowl and turn greased side up. Cover; let rise in warm place 1 to 1 1/2 hours or until double in size.
