In a large bowl of a stand mixer add water and honey. Sprinkle yeast on top. Let sit for 5 minutes.
Stir in cracked wheat, sunflower seeds, sesame seeds, wheat germ and oats.
Add oil, salt and vital wheat gluten. Mix on low speed.
Add flour 1 cup at a time, mixing between each cup. You might not need all 5 cups of flour. Once you've added 4 cups, begin adding at ¼ cup at a time until the dough comes together but isn't too dry.
Knead with mixer on a low speed for 5 minutes.
Remove dough to a greased bowl. Cover with plastic wrap or a clean dry towel.
Let rise until doubled, approximately 1 ½ hours.
Lightly punch dough down and place on a clean surface.
Divide dough in half. Shape into loaves and place in a greased bread pan.
Cover and let rise for at least 30 minutes.
Bake in a preheated 375 degree oven for 40 minutes.
Remove bread from pan 5-10 minutes after baking.
Let bread fully cool on a baking rack before slicking.
