In large bowl, combine 1-1/2 cups flour, sugar, undissolved yeast, Italian herb seasoning, and salt. Gradually add warm water and oil to flour mixture; beat 2 minutes at medium speed of electric mixer, scraping bowl occasionally. Beat 2 minutes at high speed. Stir in enough remaining flour to make soft dough. Knead on floured surface until smooth and elastic, about 4 to 6 minutes. Place in greased bowl, turning to grease top. Cover; let rise in warm, draft-free place until doubled in size, about 30 to 45 minutes. (With RapidRise Yeast, omit rising; proceed with shaping.)
Punch dough down. Remove to floured surface; roll to 14 x 10-inch rectangle. Layer ham, cheese, and salami lengthwise over center-third of dough; top with pimientos and olives. With sharp knife, make cuts from filling to dough edges at 1-inch intervals along sides of filling. Alternating sides, fold strips at an angle across filling. Place on greased baking sheet; cover. Let rise in warm, draft-free place until doubled in size, about 30 to 45 minutes.
Brush loaf with egg white; sprinkle with sesame seed. Bake at 400°F for 25 minutes or until done.
