Dice onion, celery and poblano peppers. For less spice, remove the seeds and ribs from the peppers.
If using a pressure cooker, combine all ingredients in the pressure cooker and set for 30 minutes. Once the chili is done, you can cook it in a large pot over medium heat for 30 minutes or until thickened to desiered consistency.
If using a slow cooker, combine all ingredients and cook on low for 8 hours or high for 4 hours. Again, you can transfer the chili to a large pot on the stovetop and cook for 30 minutes until thickened.
If cooking on the stovetop, combine all ingredients in a stock pot and cook on low heat for 2-3 hours, until the chili is thick and the flavors are combined.
Once the chili is cooked, taste and season with salt and more spices as needed.
Serve chili with shredded cheese, tortilla chips or potato sticks, minced red onion and sour cream.
