Combine the water, honey, and yeast and let this sit for 5 to 10 minutes so that the yeast can bloom.
Place the bread flour, whole wheat flour, oatmeal, and salt in the bowl of a mixer. Briefly whisk or stir to mix the ingredients.
Add the wet ingredients (the yeast mixture and olive oil) to the dry. Using a dough attachment, turn the mixer on low and mix until the wet ingredients are incorporated into the dry. Increase the speed to medium and knead the dough until it becomes smooth and elastic.
Remove the dough from the mixer bowl and spray the bowl with non-stick spray. Replace the dough, spritz the dough with non-stick spray, and cover the bowl with plastic wrap. Place it in a warm environment and allow it to rise for 1 hour or until doubled.
After the dough has risen, divide it into 6 balls. Roll each portion into a log 4 to 5 inches long. Place them on a baking stone or cookie sheet lined with parchment paper or Silpat. Cut two 1/2-inch slices on the tops of each loaf. Place the baking stone or sheet in the oven and allow the loaves to rise for 30 to 45 minutes.
After they have risen and while the loaves are still in the oven, turn on the oven to 350 degrees Fahrenheit. Bake the loaves for 18-20 minutes or until golden brown and cooked thoroughly. Remove them from the oven and remove to a wire rack to cool.
