DIRECTIONS

1. In a large mixing bowl, combine the flour, oats, yeast and salt. In a saucepan, heat water, molasses and butter to 120 degrees F-130 degrees F. Add to dry ingredients; beat just until moistened. Place in a greased bowl; turn once to grease top. Cover and let rise in a warm place until doubled, about 45 minutes.
2. Press dough onto a greased 14-in. pizza pan. Cover and let rise until doubled, about 30 minutes. Brush with egg. Sprinkle with onion, sesame seeds and garlic salt. Bake at 350 degrees F for 30-35 minutes or until golden brown. Remove to a wire rack to cool. Split the focaccia in half horizontally; spread mayonnaise and mustard on cut sides. On bottom half, layer lettuce, ham, cheese, onion, green pepper and tomatoes. Replace top half. Chill until serving. Cut into wedges.
