Turn a crockpot on to high heat and turn your oven's broiler on to preheat.  Place your Anaheim chiles on a baking sheet underneath the broiler.  Turn them so that they get blackened on each side.  

Once blackened all over, remove from the oven and place them immediately in a Ziploc bag.  Zip the bag closed and set aside to steam in the bag.  

In a medium skillet, crumble and brown the spicy sausage over medium to high heat.  While that is cooking, cut the block of cheese into small cubes.  These don't have to be precise.  It just allows the cheese to melt faster.  You will also need to dice an onion and mince the garlic if you are using fresh.

Place the cheese cubes in the crockpot.  Once the sausage is cooked thoroughly, layer it in the crockpot on top of the cheese.   

Get a new skillet or wipe the grease out of the one you used for the sausage and cook the bacon.  Cook until crispy and then chop into small pieces and layer on top of the sausage in the crockpot.

Remove the grease from the skillet and use the same pan to saute the onions and garlic or you can get a new skillet for this.  Once the onions are clear, place the onions and garlic in the crockpot.

Take the Anaheim peppers out of the bag and peel the skin off of each one.  Remove the seeds.  Dice into small pieces and add to the crockpot.  

At this point, the cheese should be melted enough to stir everything together.  Make sure it is combined well.  You can serve immediately or cook for a couple hours.  The longer it cooks, the more the flavors will blend together and better it will taste.
