Into a large, deep pot, over medium-high heat, add in the olive oil.
Once hot, toss in the diced onion, celery, and pepper. Cook for 5 minutes, stirring occasionally.
Add the mushrooms in and cook for another 4 minutes, stirring occasionally.
Add in the corn, jalapeno pepper, and garlic, and cook for another 2 minutes, stirring occasionally.
Combine all of the seasonings and spices into a small bowl. Dump this blend into the pot and cook for 2 minutes, stirring constantly.
Finally, add all of the beans, vegetable stock, and the entire cans of the tomato sauce and chopped tomatoes. Stir well.
Now turn the burner down to medium heat and bring the chili up to a simmer.
Once it begins to consistently simmer, turn the heat down to low, cover, and cook for 45 minutes. Stir occasionally, making sure to scrape the pot's bottom and edges to ensure nothing is sticking.
Allow the chili to cool down to room temperature before storing in containers.
