it's not a war. texans will generally advocate no beans, the rest of the country uses beans.
My basic recipe is 3 cans of chili hot beans, and another three cans of beans(regular kidney, pinto, or black beans) , You need some fresh tomatoes or use canned diced/rotel. A large diced onion, a can of tomato paste, a package of meat(ground beef, turkey, bison, lamb), and lots of spices, usually varied from pot to put, but usually cumin and cayenne for sure, some bay leaves in a tea ball, celery salt, fresh garlic, whatever else sounds fun.
also diced green peppers, habaneros, jalapenos and poblanos can be good.
