Combine water, yeast and 1 teaspoon sugar in a large mixing bowl; let sit 5 minutes for the yeast to foam. Add milk, oil, remaining sugar, salt, thyme, oregano, garlic, rosemary, whole wheat flour, oats and flax. Beat for 2 minutes. Add 1 cup all-purpose flour, olives, cheeses and tomatoes; gradually add enough remaining all-purpose flour to make a soft dough.
Knead on a lightly floured surface for 6 to 8 minutes until dough is smooth and elastic. Place in a greased bowl, turning once to coat. Cover and let rise in a warm, draft-free area for 1-1/2 hours or until double in size.
Divide dough into 32 equal pieces. Roll each into a ball and place on a greased baking sheet. Cover; let rise for 30 minutes or until doubled. Bake in a preheated 425°F oven for 10 minutes. Reduce heat to 375°F and bake for 10 to 15 additional minutes.
