Step 1: Tools and Supplies
If you don't have a sandwich press, you night be able to use your oven, although I haven't tried it.
Step 2: Slice your bread
Now remove the slices, and cook the next batch. Once they are all browned, set them aside to cool. They will be a little soft initially, but will crisp up when they cool. It's better to let them sit for an hour or so to dry out thoroughly and crisp up before putting them into a container to store.
