For the Bread: In a large mixing bowl, combine the flour, oats, yeast and salt. In a saucepan, heat water, molasses and butter to 120-130 degrees. Add to dry ingredients; beat just until moistened. Placed in a greased bowl; turn once to grease top. cover and let rise in a warm bowl until doubled in size about 45 minutes. Press dough onto a greased 14-inch 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 for 30-35 minutes or until golden brown, remove to wire rack to cool.
Split the focaccia in half horizontally; spread mayo or miracle whip on cut sides. On bottom half, layer lettuce, lunchmeat, cheese onion and veggies of your choice. Replace top half. Cover tightly with saran wrap or press n' seal. Chill until ready to serve. Cut in half and then in wedges of your size choice. This does take time, but it is delicious. If you are not going to serve right away..wait on adding the lettuce and tomatoes until ready to serve as it will make your bread watery.
