Through the years, I have tried different recipes and combined many to come up with this one. It's always a big hit:

2# ground beef
1# ground pork
1 c chopped onion
1/2 c chopped green peppers
1 - 28 oz can chopped tomatoes - undrained
1 - 28 oz tomato sauce
1 - 28 oz tomato puree
1 can tomato soup
1 - 6 oz tomato paste
1 - 4 oz can chopped green chilies
1 small can kidney beans (we don't like a lot of beans)
3 T chili powder
1/2 t salt
1/4 t pepper
1T hot pepper sauce
1-2 garlic cloves, minced
3 T Cocoa
3 T Sugar
water to thin out (I think I usually use 1-1 1/2 cups)

Brown ground beef, onion and green pepper - drain
Add remaining ingredients except the beans
Bring to a boil
Reduce heat, cover and simmer for 2 hours
Stir in beans and simmer until heated

If you like a little more heat, you can exchange the green chilies for a can of chopped jalepenos. I also add more chili powder
