In your crockpot place the chicken breasts. Season the chicken with all of the seasonings (reserve the chipotle peppers for later). Add in your onion, garlic, and jalapeno. Pour 1 cup of water or broth on top.
Cook on low 5-6 hours or high 3-4.
Remove the chicken from the crockpot. Keep the liquid in the crockpot.
Add in your peppers and some of the sauce. I ended up using 3 peppers and some of the sauce. I also added some of the sauce the refried beans we put on the tostadas.
I used my immersion stick blender in the crockpot and blended until smooth. You can pour everything into a blender if you want.
Shred the chicken and mix with the sauce.
Serve it however you want.
