A half pound of dried pinto beans. In a large dutch oven or big soup pot, use enough water to just cover the pinto beans, bring it up to a boil and let it simmer for an hour, maybe an hour and 15 minutes, let it set covered for another hour. Drain and rinse them, add them back to the pan with enough water to cover them again, and bring it to a boil. Add one of the big cans (28 ounces) of diced tomatoes, juice and all, two whole small onions diced, a green pepper finely chopped, some crushed garlic (2 cloves), a dab of cumin (about a teaspoon and a half), a half cup of chopped fresh parsley, salt and pepper to taste. If you're daring, add some cayenne pepper, but it really doesn't need it.
Brown your meat in some butter. Ask your butcher for a chili grind on the chuck and pork shoulder. It's a courser grind than hamburger. Unless you have a very, very big skillet, you'll have to brown the ground chuck (2 pounds) separately from the ground pork shoulder (pound and a half), Add to the chili mix along with a third of a cup of chili powder and let the whole thing simmer for an hour, stirring occasionally.
I serve it with oyster crackers, shredded cheese and more raw chopped onions on top, but that's optional.
