The spice level of the chilli can be controlled by removing ribs and seeds from the chiles, especially the jalapeno and anaheim. I didn't use the jalapeño because my chilli was quite spicy with just the poblano and anaheim chiles. The consistency of the chilli is up to you. I like to make ours a little loose so when we add our tortilla chips, they have something to soak into. But if you like your chilli thick and scoop able, just don't add any extra broth or water. Now, some might say that the chicken is probably not worth using after boiling, but here, the flavours are so strong that its just a texture and bulk thing. You can always use poached chicken breast or roasted chicken breast and chicken broth. I have made it both ways with very little difference in flavour.
