First of all, don’t overfill your tortilla. Anything will break when pushed to its limits.  After that, the number one way to keep your wraps from breaking is to warm up your tortillas first. A little bit of heat makes wraps much more bendy and pliable. There are a few ways to accomplish this: - Heat each tortilla in the microwave for 15-30 seconds, depending on your settings. - Use a super hot cast iron skillet to warm each tortilla. - If you need to warm up multiple tortillas at once, wrap them in foil and place them in a 300 degree oven for 10-15 minutes. - Once your tortillas are warmed, you can keep them under a dampened paper towel or cloth to hold in moisture and keep them pliable.
