I love using sprouted whole grain bread because grains that have begun to sprout make it higher in nutrients and easier to digest. The starches have been broken down and the gluten has basically been predigested. This is thanks to the enzymes that get released once sprouting starts to take place. Sourdough bread is another great option in terms of healthier choices. A tip about any bread you use! Keep the crusts. When cutting the bread, always leave the crusts on. They're what give you the crispy edges!
