Here is the basics of what I did.
Fry up onion, garlic, peppers, and celery
In a crock pot put in some crushed tomatoes, water, bbq sauce, chili powder, taco seasoning, a little brown sugar and add your fried stuff. Then add a can of rinsed black beans, kidney beans (really any kind of beans you would like) . Also I cooked up 1 cup of green lentils according to the package and added them into the chili to give it some thickness.
Towards the end of cooking I added some frozen corn.
This was very yummy served with my favorite corn bread recipe
