To begin, soak your peas in cold water overnight. The next day when you are ready to start dinner, drain the peas in a colander.
Slice your bacon into 1/2-1 inch pieces.
In a Dutch oven, melt the butter over medium heat and add in your bacon. If you are using pork bacon and sausage, omit the butter.
Let the bacon cook until it is very crispy.
While the bacon is cooking, dice up your onion and celery and grate your carrots.
When the bacon is crunchy, add the veggies to the pot. Add in the sausage, breaking it up as much as possible with a spoon.
Add in all of the remaining ingredients. Bring it to a boil, then reduce the heat to low, cover, and simmer it with the lid slightly cracked for 2 hours.
Occasionally give this a stir and monitor the thickness. If it gets too thick, add a little bit of water.
