These peppers are very hot. I find that one pepper is plenty to add a nice amount of heat to the coleslaw without being too hot. However, if you really enjoy spice you can feel free to add more of the chipotle peppers in adobo sauce to your dressing. There are multiple peppers inside each can. You can transfer the additional chipotle peppers in sauce into a freezer safe container and store it in the refrigerator, or freezer, for up to 1 month.
