Recipe Notes

If you have a smaller Crock Pot, you can you 3 tortillas instead of 4. If you want to cut out some of the grease, use ground turkey instead of ground beef. My husband doesn’t like olives, so I usually skip that ingredient in most of our recipes. I think that it would also be fun to through some jalapenos in too! Either you could cook them in the slow cooker, or put some fresh ones on top when it is done. Also, make SURE you grease the bottom of your Crock Pot before putting the tortillas in, or it will stick!
